monitor kernel deadloop enable

Use monitor kernel deadloop enable to enable kernel thread deadloop detection.
Use undo monitor kernel deadloop enable to disable kernel thread deadloop detection.
Syntax
Centralized devices in standalone mode:
monitor kernel deadloop enable
undo monitor kernel deadloop enable
Distributed devices in standalone mode/centralized devices in IRF mode:
monitor kernel deadloop enable [ slot slot-number [ cpu cpu-number ] ]
undo monitor kernel deadloop enable [ slot slot-number [ cpu cpu-number ] ]
Distributed devices in IRF mode:
monitor kernel deadloop enable [ chassis chassis-number slot slot-number [ cpu cpu-number ] ]
undo monitor kernel deadloop enable [ chassis chassis-number slot slot-number [ cpu cpu-number ] ]
Default
Kernel thread deadloop detection is disabled.

Parameters
slot slot-number: Specifies an MPU by its slot number. If you do not specify this option, the active MPU is
specified. (Distributed devices in standalone mode.)
slot slot-number: Specifies an IRF member device by its ID. If you do not specify this option, the master
device is specified. (Centralized devices in IRF mode.)
chassis chassis-number slot slot-number: Specifies an MPU on an IRF member device. If you do not
specify this option, the global active MPU is specified. (Distributed devices in IRF mode.)
cpu cpu-number: Specifies a CPU by its number. (Distributed devices in standalone or IRF
mode/centralized devices in IRF mode.)
Usage guidelines
Kernel threads share resources in kernel space. If a kernel thread monopolizes the CPU for a long time,
other threads cannot run, resulting in a deadloop.
