Nacreoushealth monitor issue
We are using custom HTTP health monitor with send string and expecting any response from back end. we have not set any receive string. But we are seeing issue that some times F5 makes pool member down. and when as part of fix web servers are restarted it takes 15 min to come up in F5. We are using default timeres (5 and 16 s).
When checked in server, seen that TCP is getting established but then most of the times HTTP connection is not getting established. Seeing time wait or close wait for those connection. When no monitor or tcp/icmp is assigned everything looks good. Any thoughts?
