Monitor not tearing down active connection
Hi,
That was a bit of surprise to me. VS with cookie insert persistence and OneConnect profile on v11.2.0HF7
Scenario:
- Member is set to port 80 but monitor is monitoring port 81
- Client has active connection downloading big file
- During download monitor detects no response from port 81 and marks member down
- But member port 80 is working so member is sending back responses to BIG-IP
- Even with member marked down BIG-IP is accepting responses from this member and passing them back to client
- Only when next request come from client (over the same connection as first one) BIG-IP is making new LB decision and choosing new member, as well as sending new cookie in reply.
Is that expected situation? I was under impression that status set by monitor is more important than actual ability to accept packets by member.
