Usage guidelines
Starvation occurs when a thread is unable to access shared resources.
The command enables the system to detect and report thread starvation. If a thread is not executed
within an 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 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.
