Server Monitor Flapping

I was wondering if there was something one could do to remove a member out of a pool after a repeated up/down state in a certain period of time?       Thanks!

You could shorten the timeout to lower the time that a pool member has to respond to a monitor. You could also use an iRule to disable a pool member when a load balancing failure occurs using LB::down in the LB_FAILED event. Or you could use passive monitors. This post has some very useful info from Matt on passive monitors:
