Subject [jira] [Created] (AMQ-5694) ActiveMQTempDestination.delete() can block forever

-----------------------------------

             Summary: ActiveMQTempDestination.delete() can block forever
                 Key: AMQ-5694
                 URL: https://issues.apache.org/jira/browse/AMQ-5694
             Project: ActiveMQ
          Issue Type: Bug
            Reporter: Endre Stølsvik


As described in AMQ-5681, we have a setup where we every 10 seconds queries the broker over
JMS for a StatisticsMessage.

This bug concerns a .. somewhat related .. problem: In that code path, we delete the temporary
reply-to queue after we've read the data.

We've now several times ended up with a peculiar situation where the thread seems to have
died. Today I grabbed a JMX console and had a look, and the thread is not dead, it is just
locked on the delete call.

We have another problem with a shared JDBC "cluster" (the "single master, hot standbys" setup),
where the nodes loose master and effectively goes down. What I believe happens, is that the
thread sends the delete message, and then goes into a blocking wait for the reply, which never
appears, probably because the broker that was master and should have sent it, is now dead.

The delete code path should probably have had some sane timeout, and just have raised some
JMSException - or something.
