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.
