> Key: AMQ-2716
> URL: https://issues.apache.org/activemq/browse/AMQ-2716
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker, Geronimo Integration, JMS client, Transport
> Affects Versions: 5.3.0
> Environment: 64bit, SuSE 11, Sun Java 1.6.0_17, Geronimo 2.2, embedded AMQ 5.3, TCP Tranport
> Reporter: TH L.
> Priority: Critical
>
> After running messaging several hours with more than 2,000,000 asynchronous send and more than1,000,000 synchronous send/reply (with temp Queue), I found about 1.5G ActiveMQConnection objects in my whole 2G memory heap (inspected with jmap and Eclipse Memory Analyzer).
> The 1.5G ActiveMQConnection objects and their referencing objects stay in heap old generation and cannot be cleaned by GC.
> By looking into those ActiveMQConnections, I found there are a huge amount of HashMaps holding temp Queue information (e.g. ActiveMQTempQueue with different sequenceId, physicalName, etc.)
> Since the ActiveMQConnections are pooled, however, why those ActiveMQTempQueues are always kept in ActiveMQConnections?
> is that a bug? or did I do something wrong (wrong setup, wrong client code)?
> My client code
> {{{
> QueueConnection connection = null;
> QueueSession session = null;
> Queue requestQueue = null;
> Queue replyQueue = null;
> QueueReceiver receiver = null;
> QueueSender sender = null;
> try {
> connection = aConnFactory.createQueueConnection();
> connection.start();
> session = connection.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
> requestQueue = getDestinationQueue();
> sender = session.createSender(requestQueue);
> replyQueue = session.createTemporaryQueue(); // using temp queue
> aRequestMessage.setJMSReplyTo(replyQueue);
> sender.send(aRequestMessage, DeliveryMode.NON_PERSISTENT, Message.DEFAULT_PRIORITY, timeToLive);
> receiver = session.createReceiver(replyQueue);
> receiver.receive();
> } catch (Exception e) {
> ...
> } finally {
> try { receiver.close(); } catch (Exception ignored) {}
> try { sender.close(); } catch (Exception ignored) {}
> try { session.close(); } catch (Exception ignored) {}
> try { connection.close(); } catch (Exception ignored) {}
> }
> }}}
