Description

  The present invention relates to a control device, an image processing device, a memory information storage control method, a memory information storage control program, and a storage medium, and more particularly, to a control device that stores memory information in an attachable / detachable storage medium when an error occurs, and an image The present invention relates to a processing device, a memory information storage control method, a memory information storage control program, and a storage medium.

  Conventionally, in a control device that executes an application program on a general-purpose OS (Operating System) such as UNIX (registered trademark), if the operation of the application program cannot be normally continued, the application program is forced from the OS. A function to terminate automatically is implemented. For example, in a general-purpose OS represented by UNIX, when a situation in which the operation of an application program cannot be normally continued occurs, a signal is transmitted to the application program, and the processing of the application program is terminated. Core dump processing is executed depending on the type of signal transmitted to the application program.

  In recent years, built-in image processing apparatuses such as small printers, facsimile machines, copying machines, and multi-function apparatuses that have previously incorporated specific functions are based on UNIX-based general-purpose OSs because of the demand for higher functionality. An OS is adopted, and core dump processing is executed when an abnormality occurs.

  The OS conventionally executes this core dump process as shown in FIG. That is, when a failure set to execute the core dump process occurs, the OS calls the core dump execution unit, and the core dump execution unit first creates the name of the core file as shown in FIG. 12 (step S1001). ). This core file name is created using the name of the application program that caused the failure, the process ID, and the like. Next, the core dump execution unit checks whether a file with the core file name can be created in the working directory of the application program to be dumped (step S1002). End core dump processing.

  In step S1002, when a file with a core file name can be created in the working directory, the core dump execution unit creates a file with the core file name (step S1003), and stores the memory information used by the application program in the OS. Is written in the file with the size of the memory block managed by the server (step S1004).

  When the memory information is written to the file, the core dump execution unit checks whether the writing is performed normally (step S1005), and when the writing is not performed normally, the core dump process is terminated.

  If the writing is normally performed, the core dump execution unit checks whether the written memory information is the last block in the memory used by the application program (step S1006). If the writing is not the last block, the process proceeds to step S1004. Returning, the memory information used by the program is processed in the same manner as described above from the process of writing the file with the size of the memory block managed by the OS (steps S1004 to S1006).

  In step S1006, if the written memory information is the last block in the memory used by the application program, the core dump execution unit ends the core dump process.

  Such core dump processing is performed by writing memory information to a large-capacity storage device such as a hard disk. In a small and inexpensive device such as an embedded device, a large-capacity storage device such as a hard disk is used. In many cases, it is difficult to use the core dump function.

  Conventionally, a technique for generating a core file suitable for a preset storage size before executing a core dump has been proposed (see Patent Document 1).

  Conventionally, a technique for outputting a core file to a remote hard disk device via a network has been proposed (see Patent Document 2).

The core file creation location notification processing unit 31b notifies the core dump processing unit 21a of the mounted location of the removable storage device 30 notified from the execution function unit 22 as the creation location of the core file.

  As described above, when the power of the image processing apparatus is turned on, the OS 11 is read from the ROM 12 into the RAM 13 by the CPU 11 and the execution of the OS 21 is started, and the basic function units 23a to 23 are started from the ROM 12 according to the configuration of the image processing apparatus. 23n and other necessary applications such as the execution function unit 22 are read and executed on the RAM 13.

  That is, the system program 40 and the application program 50 are arranged on the RAM 13 as shown in FIG. The system program 40 includes an OS 21, and the OS 21 has a core dump function unit 21 a that performs core dump processing for storing memory information (core file) in a registered core file creation location.

  The application program 50 includes the execution function unit 22, the operation control function unit 23p, the basic function units 23a and 23b, and executes application processing. The operation control function unit 23p implements the function of the operation display unit.

  Next, the operation of this embodiment will be described. The image processing apparatus 1 according to the present embodiment is configured such that when the controller board 1 has a preset situation such as when a problem occurs in the execution of an application, the memory information can be attached to the removable storage device mounting openings 19a to 19a. The core dump processing to be stored in the removable mounting device 30 mounted on the 19n is performed, but the core dump processing is stopped when the core dump processing is not in a storable state such as the mounting destination removable mounting device 30 is not mounted. Then, when it is possible to save, the core dump control process for restarting the stopped core dump process is executed.

  That is, the controller board 1 causes the OS 21 to execute a core dump function unit as shown in FIG. 4 and FIG. 5 when a malfunction that has been set in advance to execute core dump processing (core dump processing) occurs in the application program 50 being executed. 21a is called, and the core dump function unit 21a first creates the name of the memory information file (core file) to be created (step S101). The core dump function unit 21a performs the creation of the memory information file name (core file name) by using the name of the application program that caused the failure, the process ID, and the like.

  Next, as shown in FIG. 5, the core dump function unit 21a attempts to create a core file using the created core file name. In this case, the core dump function unit 21a selects a directory used for work by the program causing the failure as the creation location of the core file.

  The core dump function unit 21a determines whether or not a core file with the core file name can be created in the working directory of the target program (step S102). If the core file cannot be created, the core dump process cannot be performed, and the process is performed as it is. Exit.

  If the core file can be created in step S102, it is checked whether the removable storage device 30 can be used as a storage location and a core file can be created with the core file name in the storage location (step S103). When a removable storage device 30 having an empty area is attached to the removable storage devices 19a to 19n and a core file can be created with a core file name using the removable storage device 30 as a storage location, the storage location Write the memory information used by the application program in which the above-mentioned trouble occurs to the created core file with the size of the memory block managed by the OS 21 (step S104), and check whether the writing has been performed normally (step S105). ).

  If the writing is not normally performed in step S105, the core dump function unit 21a determines that the memory information cannot be stored, and ends the core dump process (memory information storage process).

  When the writing is normally performed in step S105, the core dump function unit 21a checks whether the written memory information is the last block in the memory used by the program (step S106). If not, the process returns to step S104 to perform the same processing as described above from the writing of the memory information (steps S104 to S106).

  In step S106, when the written memory information is the last block in the memory used by the program, the core dump function unit 21a determines that the core dump processing (memory information storage processing) has been normally completed to the end. Then, the memory information saving process (core dump process) is terminated.

  In step S103, when the removable storage device 30 is used as a storage location and a core file cannot be created with the core file name in the storage location, for example, the removable storage device 30 is not installed or is installed. When the core file cannot be created because there is no free space in the removable storage device 30 or the core file creation location is a read-only area, the core dump function unit 21a temporarily stops the core dump process, The user is notified of the stoppage by, for example, a buzzer ringing notification method such as display on a serial console, lighting of an illuminant such as an LED of an operation display unit of the image processing apparatus, or flashing, and core dump processing is resumed. (Step S107).

  As shown in FIG. 5, the user recognizes that the core dump process has been stopped by this core dump process stop notification, and in order to restart the core dump process, the user can select either the removable storage device 30 equipped with the restart function unit 31. Are attached to the removable storage device mounting openings 19a to 19n.

  The execution function unit 22 monitors whether the detachable storage device 30 is mounted in any of the removable storage device mounting ports 19a to 19n, and the mount processing execution processing unit 22a monitors the detachable storage device 30. When the detachable storage device mounting ports 19a to 19n are mounted, a mount process for causing the system to recognize the mounted detachable storage device 30 is executed. In the execution function unit 22, the application execution processing unit 22b executes a core dump processing resumption processing unit 31a that is an application mounted on the attached removable storage device 30, and the mount location notification processing unit 22c When executing the application from the removable storage device 30, the resuming function unit 31 of the removable storage device 30 is notified of the location where the removable storage device 30 is mounted on the file system. As a method of notifying the mount location from the mount location notification processing unit 22c to the resume function unit 31, for example, a method of setting an environment variable of the resume function unit 31, a method of specifying as a parameter when executing the resume function unit 31, A method using an interprocess communication function such as a shared memory function or a socket function can be used.

  When the resume function unit 31 mounted on the removable storage device 30 is executed by the application execution processing unit 22b, the core dump process restart processing unit 31a is changed to the core dump function unit 21a. A request to resume the stopped core dump process is issued, and the core dump process is resumed. When resuming the core dump processing, the resuming function unit 31 is configured such that the core file creation location notification processing unit 31b is mounted with the removable storage device 30 notified from the mount location notification processing unit 22c of the execution function unit 22. To the core dump function unit 21a of the OS 21 as a core file storage location.

  When the core dump process stopped by the resume function unit 31 is resumed, the core dump function unit 21a creates a core file in the core file storage location notified at the time of the resume (step S108). It is checked whether it has succeeded (step S109).

  If the core dump function unit 21a fails to create the core file in step S109, the core dump function unit 21a determines that the core dump process cannot be performed, terminates the process, and if the core file is successfully created, The memory information used by the generated application program is written into the created core file with the size of the memory block managed by the OS 21 (step S104), and it is checked whether the writing has been performed normally (step S105). .

  If the writing is not normally performed in step S105, the core dump function unit 21a determines that the memory information cannot be stored, ends the core dump process (memory information storing process), and the writing is performed in step S105. If it is normally performed, it is checked whether the written memory information is the last block in the memory used by the program (step S106). If it is not the last block in step S106, the core dump function unit 21a returns to step S104 and performs the same processing from the writing of the memory information as described above (steps S104 to S106). If it is the last block in the memory in use, it is determined that the memory information storage has been normally completed to the end, and the core dump process is terminated.

  As described above, when the controller board 1 of the image processing apparatus according to the present embodiment performs the core dump process (memory information storage process) that generates the memory information related to the program being executed on the memory and stores the generated memory information in the removable storage device 30. If the core dump process of the memory information to the removable storage device 30 is impossible because the removable storage device 30 is not mounted in the removable storage device mounting ports 19a to 19n, the core dump processing After that, when the core dump process to the removable storage device 30 becomes possible by connecting the removable storage device 30 or the like, the stopped core dump processing is resumed.

  Therefore, it is possible to confirm that the core dump process is ready to be executed, and to reliably save the memory information in the removable storage device 30, and to securely save the memory information in the removable storage device 30 at a low cost. be able to.

FIG. 6 shows the control of the present invention. 4 is a diagram showing a program arrangement on a ROM of a controller board and a removable storage device in an image processing apparatus to which a second embodiment of the apparatus, the image processing apparatus, the memory information storage control method, the memory information storage control program, and the storage medium is applied. FIG. .

  The present embodiment is applied to the image processing apparatus and the controller board similar to the image processing apparatus and the controller board 1 of the first embodiment. In the description of the present embodiment, Similar components are denoted by the same reference numerals, and description thereof is omitted or simplified.

  6, the ROM 12 of the controller board 1 stores the same programs of the OS 21, the execution function unit 22, and the basic function units 23 a to 23 n as in the first embodiment, and also on the removable storage device 30. Stores the program of the restart function unit 31 having the core dump process restart processing unit 31a and the core file creation location notification processing unit 31b as in the first embodiment, and also stores the program of the restart setting function unit 32. ing.

  The restart setting function unit (specifying means) 32 has a restart target description unit 32a, and the restart target description unit 32a describes a target for restarting the core dump process that the restart function unit 31 notifies the core dump function unit 21a. ing. That is, the restart setting function unit 32 identifies the core dump process to be restarted among the stopped core dump processes based on the description content of the restart target description part 32a.

  The resuming function unit 31 includes a resuming target core file process notifying unit 31c that notifies the resuming target core dump process described in the resuming target description unit 32a to the execution function unit 22 as the resuming target core dump process. .

  The controller board 1 of the image processing apparatus according to the present embodiment specifies the core dump process to be resumed from the plurality of stopped core dump processes by the resume setting function unit 32 of the removable storage device 30, and resumes the core dump process. .

  That is, as shown in FIG. 7, the image processing apparatus is set in advance to execute core dump processing (memory information storage processing) when a plurality of applications 50 (50a, 50b, etc.) are being executed. When a problem occurs in the application program 50a being executed, the OS 21 calls the core dump function unit 21a as shown in FIG. 7, and the core dump function unit 21a starts the core dump process. First, the name of the core file to be created is set. , Using the name, process ID, etc. of the application program that caused the failure.

  Next, the core dump function unit 21a uses the created core file name, selects a directory used by the program causing the failure as a creation location of the core file, and tries to create the core file. .

  The core dump function unit 21a determines whether or not a core file with a core file name can be created in the working directory of the target program. If the core file cannot be created, the core dump process cannot be performed, and thus the process ends. When the core dump function unit 21a can create the core file, the removable storage device 30 is used as a storage location, and the core dump function unit 21a checks whether the core file can be created with the core file name in the storage location, and is already removable. When the removable storage device 30 is attached to the storage devices 19a to 19n and a core file can be created with a core file name using the removable storage device 30 as a storage location, the application in which the above-described problem has occurred is stored in the storage location. The memory information used by the program is written in the created core file in the size of the memory block managed by the OS 21. When the core dump function unit 21a writes the core file, the core dump function unit 21a checks whether the writing is performed normally. If the writing is not performed normally, the core dump function unit 21a determines that the memory information cannot be stored, and performs core dump processing (memory The information storage process is terminated.

  When the core file is normally written, the core dump function unit 21a checks whether the written memory information is the last block in the memory used by the program, and if it is not the last block, the memory information When the memory information written is the last block in the memory used by the program, the core dump function unit 21a determines that the memory information storage has been normally completed to the end. Then, the memory information saving process (core dump process) is terminated.

  The core dump function unit 21a uses the removable storage device 30 as a storage location, and when the core file cannot be created with the core file name in the storage location, the core dump processing is temporarily stopped and the core dump processing is stopped. For example, display to a serial console, lighting of a light emitting body such as an LED of an operation display unit of an image processing apparatus, blinking, etc. wait.

  When a failure that is set in advance to execute the core dump process (memory information storage process) occurs in the other application program 50 being executed, for example, the application 50b, while the one core dump process is stopped, the OS 21 Similarly, the core dump function unit 21a is called, and the core dump function unit 21a starts the core dump process. The core dump function unit 21a processes the core dump process in the same manner as described above, and when the core file cannot be created, the core dump process is temporarily stopped, and the fact that the core dump process has stopped is displayed on the serial console, for example, The user is notified by a buzzer ringing notification method such as lighting or blinking of a light emitter such as an LED of the operation display unit of the image processing apparatus, and waits for the core dump process to be resumed.

  The user recognizes that the core dump process has stopped by the core dump process stop notification, and in order to restart the core dump process, the user attaches the removable storage device 30 equipped with the resume function unit 31 to any one of the removable storage device mounting ports 19a. Attach to ~ 19n. At this time, the removable storage device 30 includes not only the resume function unit 31 but also the resume setting function unit 32 having a resume target description unit 32a that is a description related to the core dump process to be resumed.

  The restart target description unit 32a is a description that is performed to specify the core dump process that the user wants to restart. As a method for specifying the core dump process to be restarted, for example, a method of specifying by the file name of the application program that caused the failure A method of specifying by a process ID, a method of resuming one process at random from the stopped core dump processes, and the like can be used. For example, when a certain phenomenon has occurred, if the target of the core dump process is known, the method specified by the process ID or the method specified by the program file name can be used. If there are multiple processes in the program, and multiple processes out of those multiple processes are in the process of stopping core dump processing, when the process that you want to acquire the core file is known, the process ID An identifying method can be used. In addition, when it is known that a large-capacity removable storage device 30 can be used and a core file can be stored by all core dump processing, all stopped core dump processing is restarted. May be. Furthermore, when it is not clear which process is stopping the core dump process, one core dump process may be specified at random from the stopped core dump processes and restarted.

  The execution function unit 22 monitors whether the detachable storage device 30 is mounted in any of the detachable storage device mounting ports 19a to 19n, and the mount processing execution processing unit 22a monitors the detachable storage device 30. When the detachable storage device 30 is attached to the detachable storage device attachment ports 19a to 19n, a mount process for causing the system to recognize the attached detachable storage device 30 is executed. In the execution function unit 22, the application execution processing unit 22b executes a core dump processing resumption processing unit 31a that is an application mounted on the attached removable storage device 30, and the mount location notification processing unit 22c When the application is executed from the removable storage device 30, the permission function unit 31 of the removable storage device 30 is notified of the location where the removable storage device 30 is mounted on the file system. As a method of notifying the mount location from the mount location notification processing unit 22c to the resume function unit 31, for example, a method of setting an environment variable of the resume function unit 31, a method of specifying as a parameter when executing the resume function unit 31, A method using an interprocess communication function such as a shared memory function or a socket function can be used.

  Then, the resume function unit 31 mounted on the removable storage device 30 resumes when the application execution processing unit 22b of the execution function unit 22 executes the core dump process restart processing unit 31a of the resume function unit 31. The resume target description part 32a of the function part 32 is read to identify the core dump process to be resumed among the stopped core dump processes, and the resumed core file process notification part 31c performs the identified core dump process by the core dump function of the OS 21. And the core file creation location notification processing unit 31b uses the location where the removable storage device 30 notified from the mount location notification processing unit 22c of the execution function unit 22 is mounted as the core file storage location. , The core dump function unit 21a of the OS 21 is notified.

  When the identified core dump process is resumed among the core dump processes stopped by the resume function unit 31, the core dump function unit 21a creates a core file in the core file storage location notified at the time of the resume, and the core file Check if the creation is successful.

  If the core dump function unit 21a fails to create the core file, the core dump function unit 21a determines that the core dump process cannot be performed, ends the process, and if the core file is successfully created, the application in which the above-described problem occurs is stored in the storage location. The memory information used by the program is written into the created core file with the size of the memory block managed by the OS 21 to check whether the writing has been performed normally.

  When the writing is not normally performed, the core dump function unit 21a determines that the memory information cannot be stored, ends the core dump process (memory information storing process), and writes the data when the writing is normally performed. Check if the memory information is the last block in memory used by the program. When it is not the last block, the core dump function unit 21a performs the same processing from the writing of the memory information as above, and if the written memory information is the last block in the memory used by the program, the memory information is stored last. It is determined that the process has been completed normally, and the core dump process is terminated.

  As described above, the controller board 1 of the image processing apparatus according to the present embodiment includes the restart setting unit 32 including the restart target description unit 32a that identifies the stopped core dump process in the removable storage device 30, and the restart function unit. 31 restarts the core dump process specified by the restart setting unit 32 among the core dump processes stopped by the core dump function unit 21a of the OS 21.

  Therefore, since the stopped core dump process can be selectively restarted, a removable storage device 30 having a memory size required for the core dump process to be resumed among a plurality of stopped core dump processes is prepared. The memory information can be stored without using an expensive and large-capacity storage device by executing the core dump process by mounting the removable storage device mounting ports 19a to 19n.

  Further, in the controller board 1 of the present embodiment, the restart setting unit 32 mounted on the removable storage device 30 identifies the stopped core dump process by the process ID or the program file name of the program from which the stopped core dump process is generated. Or, all of the plurality of core dump processes being stopped are specified.

  Therefore, the core dump process to be resumed can be specified using an appropriate specifying method among a plurality of specifying methods, and appropriate core dump processing can be executed while improving the usability.

  Then, when only a part of the core dump processes is restarted among the plurality of core dump processes being stopped as described above, the other core dump processes that have not been restarted remain in the stopped state.

  Therefore, once the core file is acquired, the acquired core file is moved to another device (for example, a computer, etc.), the free space of the removable storage device 30 is increased, and the removable storage device is mounted again. When the removable storage device 30 is attached to the light 19a to 19n and the core file can be obtained in the same manner as described above, even when the removable storage device 30 does not have a large-capacity storage area, All core files can be sequentially dumped into the removable storage device 30 for processing.

  8 to 11 are diagrams showing a third embodiment of the control device, the image processing device, the memory information storage control method, the memory information storage control program, and the storage medium of the present invention, and FIG. 8 shows the control of the present invention. 7 is a diagram showing a program arrangement on a ROM of a controller board and a removable storage device in an image processing apparatus to which a third embodiment of the apparatus, the image processing apparatus, the memory information storage control method, the memory information storage control program, and the storage medium is applied. FIG. .

  The present embodiment is applied to the image processing apparatus and the controller board similar to the image processing apparatus and the controller board 1 of the first embodiment. In the description of the present embodiment, Similar components are denoted by the same reference numerals, and description thereof is omitted or simplified.

  The image processing apparatus according to the present embodiment performs a core dump process control process (memory information storage control process) that can be interrupted by designating a stopped core dump process.

  In FIG. 8, on the ROM 12 of the controller board 1, the same programs as the OS 21, execution function unit 22, basic function units 23a to 23n and UI (user interface) control unit 24 are stored. In addition, on the removable storage device 30, a restart function unit 31 having a core dump process restart processing unit 31a, a core file creation location notification processing unit 31b, and a restart target core file processing notification unit 31c similar to those in the second embodiment, and A program of the restart setting function unit 32 having the restart target description unit 32a is stored.

  The UI control unit (notification unit, interruption unit) 24 includes a stopped core dump processing display processing unit 24a, a stopped core file processing interruption option display processing unit 24b, and a stopped core dump processing interruption notification processing unit 24c. The stopped core dump process display processing unit 24a displays that the core dump process has stopped on the display unit of the operation display unit which is a UI (user interface) of the image processing apparatus when the core dump process being executed by the core dump function unit 21a is stopped. Then, the stopped core file processing interruption option display processing unit 24b displays an option for interrupting the stopped core dump processing on the display unit of the operation display unit. The suspended core dump process interruption notification processing unit 24c issues an interruption request of the core dump process selected to be suspended by the suspended core file process interruption option display processing unit 24b to the core dump function unit 21a to be interrupted.

  The controller board 1 of the image processing apparatus according to the present embodiment performs an interruption process for interrupting the stopped core dump process as illustrated in FIGS. 9 and 10 in accordance with selection on the UI. In FIG. 9, the same step numbers are assigned to the same processing steps as those in FIG. 4 of the first embodiment, and the description thereof is simplified.

  That is, as shown in FIG. 9 and FIG. 10, the image processing apparatus is set to execute a core dump process (memory information storage process) in advance in the application 50 being executed. The core dump function unit 21a is called, and the core dump function unit 21a starts the core dump process. First, the name of the core file to be created is created by using the name of the application program that caused the failure, the process ID, and the like (step) S101).

  Next, the core dump function unit 21a uses the created core file name, selects a directory used by the program causing the failure as a creation location of the core file, and tries to create the core file. .

  The core dump function unit 21a determines whether or not a core file with the core file name can be created in the working directory of the target program (step S102). If the core file cannot be created, the core dump process cannot be performed, and the process is performed as it is. Exit. In step S102, when the core dump function unit 21a can create the core file, the core dump function unit 21a checks whether the removable storage device 30 can be used as a storage location and the core file can be generated with the core file name in the storage location. (Step S103) If the removable storage device 30 is already attached to the removable storage devices 19a to 19n, and the core file can be created with the core file name using the removable storage device 30 as a storage location, the storage is performed. The memory information used by the application program in which the above-described defect has occurred is written in the created core file in the size of the memory block managed by the OS 21 (step S104). When the core file is written, the core dump function unit 21a checks whether the writing is performed normally (step S105). If the writing is not performed normally, the core dump function unit 21a determines that the memory information cannot be stored. End core dump processing.

  When the core file is normally written in step S105, the core dump function unit 21a checks whether the written memory information is the last block in the memory used by the program (step S106). If it is not the last block, the same processing as described above is performed from the writing of the memory information (steps S104 to S106). In step S106, when the written memory information is the last block in the memory used by the program, the core dump function unit 21a determines that the core dump process has been normally completed to the end, and ends the core dump process. To do.

  In step S103, when the removable storage device 30 is used as a storage location and a core file cannot be created with the core file name in the storage location, for example, the removable storage device 30 is not installed or is installed. When the core file cannot be created because there is no free space in the removable storage device 30 or the core file creation location is a read-only area, the core dump function unit 21a pauses the core dump process, and the core dump function unit When 21a stops the core dump process, the UI control unit 24 displays that the stopped core dump process display processing unit 24a indicates that the core dump process has been stopped on the display unit of the operation display unit of the image processing apparatus, and the stopped core. The file processing interruption option display processing unit 24b is displayed on the display unit of the operation display unit of the image processing apparatus. For example, to display the stop notification-interruption selection screen as shown in FIG. 11, or core dump process is resumed, interrupted is selected operations, checks whether interrupting function is called (step S201). The method in which the core dump function unit 21a of the UI control unit 24 receives the notification of the core dump process stop from the core dump function unit 21a is, for example, that the UI control unit 24 constantly monitors the core dump process stop notification from the core dump function unit 21a. A method for synchronously receiving a core dump processing stop notification, a method for receiving a core dump processing stop notification asynchronously as in a signal function, or a periodic inquiry to the OS 21 to confirm whether there is a stopped core dump processing. A method or the like can be used. The core dump function unit 21a notifies the UI control unit 24 of the stop of the core dump process by directly notifying the UI control unit 24 from the OS 21 or first notifying another program (for example, the execution function unit 22). From there, a method of notifying the UI control unit 24 can be used.

  When the UI control unit 24 receives the core dump processing stop notification from the core dump function unit 21a, the UI control unit 24 displays on the stop notification / interruption selection screen that the core dump processing has stopped due to a problem, and notifies the user. In addition to notifying the occurrence of a problem, an interrupt button (interrupt option) that enables interrupting the stopped core dump process is presented on the screen to check whether the interrupt function has been selected (step S202).

  The user selects interruption on the stop notification / interruption selection screen as shown in FIG. 11, or attaches the removable storage device 30 equipped with the resume function unit 31 to any of the removable storage device mounting ports 19a to 19n. Installing.

  When the user attaches the removable storage device 30 to any of the removable storage device attachment ports 19a to 19n, it is determined in step S202 that the resumption of the stopped core dump process is selected, and the same as in the second embodiment. Restart the stopped core dump process.

  When the user selects the interruption on the stop notification / interruption selection screen, the UI control unit 24 sends the suspended core dump processing interruption notification processing unit 24c to the core dump function unit 21a of the OS 21 in response to the interruption request of the core dump processing selected to be interrupted. put out.

  When there is an interruption request from the suspended core dump process interruption notification processing unit 24c of the UI control unit 24, the core dump function unit 21a interrupts the core dump process related to the interruption request and ends the core dump process (step S203).

  As described above, when the core dump function unit 21a of the OS 21 stops the core dump process, the controller board 1 of the present embodiment notifies that fact on the display unit of the UI control unit 24.

  Therefore, without using a special device such as a serial terminal (serial console), the user can know that a problem has occurred in the processing of an application such as an image processing device and the user has stopped. The user can recognize that the information can be acquired and can appropriately acquire the memory information.

  In addition, the controller board 1 according to the present embodiment is configured so that the core dump process stopped by the core dump function unit 21a is stopped by the selection according to the display of the stopped core file processing interruption option display processing unit 24 of the UI control unit 24. The suspension notification processing unit 24c makes a suspension request to the core dump function unit 21a, and the core dump function unit 21a suspends the core dump processing for which the suspension request has been made.

  Therefore, the acquisition of unnecessary memory information can be interrupted by the user, and unnecessary memory information continues to exist in the memory indefinitely, avoiding a state in which a normally operating program presses the usable memory area. can do.

  The controller board 1 according to the present embodiment is applied to a case where a UNIX-based OS is used as an OS and a core dump, which is a memory information saving process, is performed using the function of the OS.

  Therefore, information necessary for analysis can be acquired in a commonly used format, and existing software for analyzing the acquired information can be used. As a result, the memory information storage control of the present invention can be introduced simply and easily.

  The OS is not limited to a UNIX-based OS, and is an OS that is equipped with the core dump processing function (memory information storage function) or that can be added by an application program. Any OS may be used.

  Furthermore, the image processing apparatus according to the present embodiment includes a controller board 1 as a control apparatus mounted on an image processing apparatus that performs predetermined image processing on image data.

  Accordingly, the memory information necessary for analyzing the operation of the image processing apparatus can be appropriately stored in the removable storage device 30, and the analysis of the image processing apparatus can be performed reliably and efficiently.
