Ok, at least the stack trace is clear. The session has been invalidated somehow. We would need to figure out when and how this happens, is it possible that you are doing a clean shutdown of a tomcat instance and that instance expires all the sessions? If that is the case, kill the tomcat with 'kill -9' to simulate a failure. there is a flag called 'expireSessionsOnShutdown', do you have that set?
