mod_cluster session draining does not work

Environment

• JBoss Enterprise Application Platform (EAP) 6.x

Issue

• We use mod_cluster and its session draining. mod_cluster always takes the full stop-context-timeout to drain sessions even though all sessions certainly were invalidated before then.

Resolution

• Apply the 6.4.8 CP

Root Cause

  • mod_cluster uses a session listener to be notified when a session expires. That listener was not properly added so it was not invoked. But if that listener is invoked, mod_cluster would still see the session as active because the listener is invoked before sessions are removed. Thus, mod_cluster's session drain always takes the full amount of time.
