Aantat I believe the issue you are experiencing is when your pool member is transitioning from green (healthy) to red (failed). These connections will always drop because the F5 still thinks the device is alive because the health monitor hasn't failed yet but is in the process of failing and I do not believe you can get around this at all other than the connections dropping because the F5 doesn't transition a client from one pool member to another until the health monitor fails completely.

CirrusHi, I think below option will help.
first option is 'time until up' in monitor.
second option is 'manual Resume' in monitor

CirrusHi Hooni_L.
I'm facing problem not when node becames available. I'm facing it when node is going down. I confgirud "Action on service down" to Reselect, but I'm still losing 2-3 requests which is critical. My goal is IF one of the nodes is going down - requests goes to another node without losing that request. I hope I made it clear
