rdisp/rfc_max_wait_time
Definition
Maximum period of time in seconds that the system waits after a load check. The wait time is calculated based on the amount of available resources. The fewer resources that are available, the longer the wait time.
Use
You can increase the wait time if you suspect that a resource bottleneck is about to occur, and if you cannot resolve the bottleneck and are prepared to accept a longer wait time.
Unit: seconds
Default value: 10
