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.
This command enables the device to detect deadloops. If a thread occupies the CPU for a specific
interval, the device considers that a deadloop has occurred. It outputs a deadloop message and reboots
to remove the deadloop.
Inappropriate use of this command can cause service problems or system breakdown. Make sure you
understand the impact of this command on your network before you use it.
