Pool members that are down are not marked down by the monitor. The BIG-IP system continues to attempt to monitor the object.
Incorrect monitor state. Pool members may not be marked down even though the target pool-member is down.
It is not known exactly what triggers this condition. It was encountered on an HTTPS monitor.
No known workaround.
The monitor process no longer inadvertently skips processing monitor timeouts and correctly marks monitored objects down.
