Expired Sessions Not Being Cleaned-Up
by Brandon Harper
Hello all,
While I've used Tomcat in the past, JBoss is still pretty new to me so
hopefully I'm going down the right path here with troubleshooting as
well as my questions.
My team is in the process of wrapping-up a new website implemented in
Apache Wicket 1.3b, Spring, and Hibernate. Each time a Wicket session
is initiated, it creates a new one under:
server/default/work/jboss.web/localhost/_/Website-filestore
Under this path a directory gets created with the id of each session,
of which each dir contains a file called pm-null.
The problem we're seeing is that nothing is cleaning-up the session
created directories once they have expired. Each session should
expire after an hour, yet I see sessions sticking around since over 5
days ago— even if the server has been stopped and restarted, runs for
days straight, gets new WAR's deployed, etc.
Being new to JBoss and after searching various mailing lists, etc, I'm
not finding much information about this. I also greped through all of
the JBoss config files but was unable to find anything of substance,
but most likely I missed something. Any suggestions on where to look
/ why I'm seeing this behavior?
Thanks,
- Brandon
