Hi,

 

Depending on your configuration, this may be an expected issue.

 

If you are you making the node down from Big IP, then what you see is expected because of that:

 

Sol13310

 

When set to Disabled, a node or pool member continues to process persistent and active connections. It can accept new connections only if the connections belong to an existing persistence session.

 

When set to Forced Offline, a node or pool member allows existing connections to time out, but no new connections are allowed.

 

But if you are really disconnecting the server (remove cable or shutdown service or whatever that makes it unreachable from the Big IP), then depending on your health monitor check status and configuration you may still have connections going to an unreachable node until the monitor times out (default 16 seconds). I assume that you have health monitoring configured.
