Send message before connection close on idle timeout

There really is no way to do that, since (as you mention) there is no iRule trigger when the connection is reaped.

 

 

Disabling idle timeout is not recommended. If no timeout is enforced, then there is no mechanism for clearing out stale entries from the connection table, and over time, the table will grow too large for LTM to handle and force a failover/restart. The connection table is cleared on failover/restart, so the condition would be alleviated temporarily, but at the expense of losing all existing connections. (Took a long time to track this one down the first time I encountered it -- just looked like random restarts until we found an idle timer for ssh sessions to backend servers was set to 0.)
