Configuring kernel thread starvation detection
CAUTION:
HP recommends using the default settings. Inappropriate configuration of kernel thread starvation
detection can cause service problems or system breakdown. Make sure you understand the impact of this
configuration on your network before you do it.
Starvation occurs when a thread is unable to access shared resources.
Kernel thread starvation detection 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
generates a starvation message.
Thread starvation does not impact system operation. A starved thread can automatically run when
certain conditions are met.
