[ https://issues.jboss.org/browse/AS7-4260?page=com.atlassian.jira.plugin.s... ] Paul Ferraro commented on AS7-4260: ----------------------------------- Actually, it looks like some fishy is going on... Looking at the stacktrace, the session as fetched from the distributed cache is invalid - meaning it's timestamp is older than the maxInactiveInterval, hence the call to ClusteredSession.expire(...). So, my question is, does your test attempt to access a session that would have been expired? Even though this condition should not cause a TimeoutException, I want to make sure there isn't something more fundamental that's broken. -- This message is automatically generated by JIRA.

From what I can tell, after failure of the lock holder, the node to which the request failed over can't get the lock, resulting in the exception. It may be that the lock state is not being updated in a timely manner, post failure. Going to look at dumping the lock states.

[ https://issues.jboss.org/browse/AS7-4260?page=com.atlassian.jira.plugin.s... ] Richard Achmatowicz commented on AS7-4260: ------------------------------------------ Still looking into this one. What I can see happening is as follows: 1. when a failover occurs, a new jvmRoute is being computed by (i) looking up the cache to get the DistributionManager (ii) finding out which addresses own the session key (iii) use the JvmRouteRegistry to look up the new jvmRoute for the key, using the address of the key 2. the jvmRoute is then adjusted and the request continues processing on the node which it arrived at 3. when the request is returned, the load balancer then uses the new jvmRoute to process the request For example: {noformat} 11:49:46,418 TRACE [org.jboss.as.web.session.JvmRouteValve] (ajp-perf18-10.16.90.54-8009-361) checkJvmRoute(): check if need to re-route based on JvmRoute. Session id: mdbFou-te-0qzdaY1T6FXyaw.perf21 jvmRoute: perf18 11:49:46,418 TRACE [org.jboss.as.web.session.JvmRouteValve] (ajp-perf18-10.16.90.54-8009-361) handleJvmRoute(): We have detected a failover with different jvmRoute. old one: perf21, new one: perf18. Will reset the session id. ... 11:49:46,420 TRACE [org.jboss.as.web.session.JvmRouteValve] (ajp-perf18-10.16.90.54-8009-361) resetSessionId(): changed catalina session to= [mdbFou-te-0qzdaY1T6FXyaw.perf19] old one= [mdbFou-te-0qzdaY1T6FXyaw.perf21] {noformat} In the above, the request arrives at perf18, the jvmRoute assigned is perf19 (based on key ownership), but the request processing is completed at perf18 until the request is returned. In processing at perf18, perf18 will have to take the global lock. If for some reason, the global lock were not being released, then the next time the request was processed by perf19, it would not be able to obtain the lock and the exception would occur. This would at least explain how two requests involving the same session were arising. Unfortunately, when I add TRACE logging to try to see more of what is going on, the exceptions do not occur. -- This message is automatically generated by JIRA.
