Value, if so, then judges that described arbitrary kernel breaks down；Described overload state is that the utilization rate of kernel is more than default use
The state of rate threshold value.
For example, a certain kernel is under 100% utilization rate state for a long time, then it is believed that described a certain kernel occurs in that
The problem of endless loop.
Whether the operation duration of the arbitrary thread in detection kernel is more than the second preset duration threshold value, if so, then judges institute
State arbitrary thread to break down.
