1. Note that there can be
"Session does time-out shorter than setting in web.xml when
PersistentManager is used. "

2. Maybe implementing a javax.servlet.http.HttpSessionListener will
allow you to catch the circumstances when your issue happens.  Note,
that if you add it to ${catalina.base}/conf/web.xml, it will be
present in all the web applications deployed on your server.

That is, if the session actually expires on the server.

Do you have any evidences on what actually happens? E.g., you can
iterate over request headers to see if the cookie is actually present,
and what path it contains, etc.
