monitor kernel starvation enable [ slot slot-number [ cpu cpu-number ] ]
undo monitor kernel starvation enable [ slot slot-number [ cpu cpu-number ] ]
In IRF mode:
monitor kernel starvation enable [ chassis chassis-number slot slot-number [ cpu cpu-number ] ]
undo monitor kernel starvation enable [ chassis chassis-number slot slot-number [ cpu
cpu-number ] ]
Default
Kernel thread starvation 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. (In standalone 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. (In IRF mode.)
cpu cpu-number: Specifies a CPU by its number.
Usage guidelines
Starvation occurs when a thread is unable to access shared resources.
The command enables the system to detect and report thread starvation. If a thread is not executed
within an interval, the system considers that a starvation has occurred, and outputs a starvation
message.
Thread starvation does not impact system operation. A starved thread can automatically run when
certain conditions are met.
Inappropriate use of the command can cause service problems or system breakdown. Make sure
you understand the impact of the command on your network before you use it.
