Parameters
slot slot-number: Specifies an MPU by its slot number. If you do not specify this option, the active MPU is

Usage guidelines
Starvation occurs when a thread is unable to access shared resources.
This command 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 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 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.
Examples
# Enable kernel thread starvation detection.
