sessionListener.sessionDestroyed is called on shutdown of a node in the cluster

[Ronald Klop]

Hello,

When I shutdown a node in my cluster (tomcat 5.5.26) sessionDestroyed is called 
on all SessionListeners on that node.
But I'm running a cluster, so one node stopping doesn't mean the session is 
destroyed.

My understanding is that expireSessionsOnShutdown="false" by default and I 
don't change it in my config.

Is this a bug, a feature or am I doing something wrong?

Ronald.
