Displaying And Maintaining Kernel Threads - H3C SR6600-X Configuration Manual

Step
2. Enable kernel thread
starvation detection.
3. (Optional.) Set the interval
for identifying a kernel
thread starvation.
4. (Optional.) Disable kernel
thread starvation detection
for a kernel thread.
To configure kernel thread starvation detection (in IRF mode):
Step
1. Enter system view.
2. Enable kernel thread
starvation detection.
3. (Optional.) Set the interval
for identifying a kernel
thread starvation.
4. (Optional.) Disable kernel
thread starvation detection
for a kernel thread.
