Usage guidelines
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.
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.
This command enables the device to detect deadloops. If a thread occupies the CPU regularly, the
device considers that a deadloop has occurred.

# Enable kernel thread deadloop detection.
