[jboss-user] [Tomcat, HTTPD, Servlets & JSP] - Http Session expiration

Scenario:

2 non-clustered JBoss servers.
Stateless sessions.

We have a development and staging duplication of servers as well as a hosted production environment.

The only difference in our production environment is our ISP uses a different firewall and hardware load balancer.

We are seeing the sessions timeout before they are scheduled to timeout ( a 4 hour timeout timing out after 1 hour ).  The session is being set in the application using session.setMaxInactiveInterval(clientTimeout * 60);

We suspect the firewall is possibly killing the sessions due to TCP session inactivity... possibly...

QUESTION:

Has anyone seen such a scenario?
If so, how did you resolve?

If we suspect incorrectly, is there something we could be overlooking which could be expring the sessions?  As we said - same config and code deployment, works properly in other 2 envisonments.

Please advise.

Thank you.
