    TimerService: Timer interval stops after retry

    Mario Klaver Newbie

      Hello,

       

      We are running into a problem concerning the EJB 3.x timer service. We are noticing the timer doesn't fire timeouts anymore after an exception has occured and the retry of the current timeout isn't finished before the new timeout should occur.

       

      We attached two source file, which will demonstrate the problem.

       

      In short:

      The execute method in the attached example gets called every minute. The first time it will throw an exception to enter the retry. When entering the retry it will sleep for 90 seconds to make sure it is not finished before the next timeout occurs.

       

      After the retry finished, new timeouts will not occur. We would expect new timeouts after the retry finished, but this doesn't happen. Can anyone explain why?

       

      We run the example on:

      - JBoss 6.0

      - with JRE 1.6.0_26

       

      Below you will find the logging:

          Mario Klaver Newbie

          We added some more logging. As you can see, the state of the timer is RETRY_TIMEOUT until the retry succeeds. After the TimerTestBean finishes the state is changed to ACTIVE. However, no new timeouts arrive, even though nextExpiration=Tue Dec 06 17:36:00.

           

          Thanks in advance,

            Dee Kay Newbie

            Did you solve it? We're facing the same problem.

            And however...we couldn't identify the cause for that timeout.

             

            Kind regards

              No it will not be fixed in jboss 6.

               

              See https://community.jboss.org/message/641355

               

              It will be fixed in jboss 7.

               

              In the provided thread three alternative workarounds are given.
