Abstract
PURPOSE:To prevent a system from running away by applying an interruption and stopping the system when 1st and 2nd check means decide that a stack position is out of a stack area or that the border flag of a task is broken. CONSTITUTION:A scheduler 5 checks whether or not the stack positions of tasks A-C are beyond the borders of the stack areas of tables 61-63 indicating the states of the tasks A-C when an interruption S1 for the tasks A-C under control is initiated. When they are within the ranges, it is checked whether or not the border flags of the stack areas 71-73 are rewritten. When the stack positions of the tasks A-C are beyond the borders of the stack areas or when the border flags of the stack areas 71-73 are rewritten, the system is stopped. Consequently, an initial system runaway is precluded and which of the task A-C is broken is known.
