Vaadin Session Timeouts happening before the session timeout

Vaadin 6 / 7 / 8
1

Good Morning,
I’m running into an issue where the session is timing out anywhere between 5 and 20 minutes. This is happening very sparatically. About half the time, the session is timing out at 90 minutes (from web.xml). After thinking that the heartbeat could’ve caused this, I disabled the heartbeat and received the same results. Have anyone else experienced this?

My web.xml currently contains the following:
Enable Session TimeoutcloseIdleSessionstrue
90 heartbeatInterval -1

The configuration that we’re using is VAADIN 7.7.3/Tomcat 8.0.41. I have the application setup for Long Polling. I searched through the log files and there are no issues being reported.

Any help would be greatly appreciated.

Thanks,
-Jeff

This was an issue with load balancing rather than Vaadin. This has been fixed and the application session timeouts are now active.
