Starvation occurs when a thread is unable to access shared resources.
Kernel thread starvation detection enables the system to detect and report thread starvation. If a thread
is not executed within a specific interval, the system considers that a starvation has occurred, and
generates a starvation message.
Thread starvation does not impact system operation. A starved thread can automatically run when
certain conditions are met.
To configure kernel thread starvation detection:
Step
Command
Remarks
1.
Enter system view.

2.
Enable kernel thread
starvation detection.

]
By default, the function is
disabled.
3.
(Optional.) Set the interval
for identifying a kernel
thread starvation.
monitor kernel starvation time
interval
[

]
The default is 120 seconds.
4.
(Optional.) Disable kernel
thread starvation detection
for a kernel thread.

After enabled, kernel thread
starvation detection monitors
all kernel threads by default.
