Greg Sheremeta of Red Hat reports:
We've found a scenario a webadmin session won't timeout and force a logout. We had a CVE on this before.
To duplicate: navigate to the Data Centers tab. Select a data center. Switch to another browser tab and wait longer than the engine timeout period  to switch back to webadmin. You won't be logged out -- even though you should be.
Basically, idling while certain things in the UI are selected (a data center, a cluster -- maybe others?) will prevent the session from timing out. We see three gluster queries that are repeating and keeping the session open. Alexander is looking for others. We know the fix -- just have to find them all.
