Subject [jira] Created: (AMQ-1979) Temporary queue on slave not removed in Pure Master/Slave setup
Date Tue, 14 Oct 2008 12:57:52 GMT
Temporary queue on slave not removed in Pure Master/Slave setup
---------------------------------------------------------------

                 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
         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.
