    connection close problem.

    senthil kumar Newbie

      Hi,

      We have deployed jboss-4.2.3.GA with jboss-messaging-1.4.0.SP3 in our production environment.

      In our application,we have developed with recivers are restarting automatically for every 15 minutes(configurable). In this case, when restarting, we are closing all the objects are session, subscriber, connection.

      Problem as when we close the connection obejct, it takes around 1 hour at some time(not all the time). We don't know the reason why it takes that much of time.

      Please some help me.

      Thanks in advance.

            Thanks for your response.

            We have analyzed and find out that, we are getting the same problem for below scenarios,

            1. To get the connection from JBoss.
            2. To register the subscribers after the getting the connection
            3. Close the connection.

            Here i pasted the Thread dump when get the connection(receiver gets hang).

              Hi,

              Sometimes my consumer also gets disconnected for some reason and is unable to reconnect. I'm using the ExceptionListener. When I detect this I try to connect another consumer and it gets stuck on the same line :

              ...
              MicroSocketClientInvoker.java:962
              ...

                Hi,

                Do you have a working test with it? It would be much easier to find the problem if there is some test.

                I suggest you also post it to remoting forum as I think it's like a remoting issue.

                  Hi,

                    i have the same problem "java.util.concurrent.locks.LockSupport.park(LockSupport.java:158)" and messages got stucked with state "+".

                    This just happen when i use Transactional connections to the queues.

                    Anyone can help?
