Hi, Two of our servers reached max heap and we had to restart to resolve the issue. In troubleshooting, we noticed Http Sessions had stopped expiring 05/12th and reached 25K over a period of 11 days. I noticed the same behavior in both servers, the session expiration seem to have stopped on both of them around the same time. I'm saying this because from looking at the monitoring graphs (NewRelic) I notice the http sessions starting to climb on both servers around the same time frame. I am thinking, the issue could be two folds: #1 - The session expiration stopped working -OR #2 - The sessions themselves were created with TTLs way into the future I suspected #1. I looked that tomcat 7.0.40 source code, extracted all session/manager error messages and searched for them in the logs and didn't find any hits. I was hoping to find something about "Session expiration stopped working", but didn't find any. Can you please advise how to troubleshoot this issue? I'd very much appreciate the help. thanks, Stephen
