Hans Bausewein commented on AMQ-1979:
-------------------------------------
Maybe it's removed later by some other cleanup method?
The application, where I've found it is running in JBoss and I suppose JBoss
keeps the open connection in a pool, so then the temporary destinations are not
removed.
Problem is that it causes a difference between the master and the slave: on the
master the queue is removed, but on the slave it still exists.
I can reproduce that with this code.
I don't have a problem with this issue anymore, because I've fixed our client
code, but I suppose the same error will be made again and will keep causing
headaches. (it was worse in our case, because the exception on the failing
delete attempt was not logged)

> Key: AMQ-1979
> URL: https://issues.apache.org/activemq/browse/AMQ-1979
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker
> Affects Versions: 5.2.0
> Reporter: Hans Bausewein
> Assignee: Gary Tully
> Attachments: activemqjee-0.0.6-src.tar.gz
>
>
> Maybe not the most logical client code, but it happened here and I guess it
> will happen somewhere again:
> TemporaryQueue reply = session.createTemporaryQueue();
> MessageConsumer consumer = session.createConsumer(reply);
> Message received = consumer.receive(timeout);
> ...
> reply.delete();
> consumer.close();
> I've removed try/finally blocks to keep it simple.
> See the attached source code.
> It works fine, but set
> JmsMessageHandler.REVERSE_ORDER=true
> and the slave will not be cleaned up properly.
> It means that the number of threads is increasing and at some time it will
> get an OutOfMemoryError (see AMQ-1849) and the slave dies.
