I have a weird JMS problem where after sending n messages to a Topic I get an OutOfMemoryError. I noticed this problem using jboss 3.2.1 using the JVM InvocationLayer.
My publisher looks like:
topicConnectionFactory = (TopicConnectionFactory) jndiContext.lookup("jvm_ConnectionFactory");
topic = (Topic) jndiContext.lookup("Topic");
topicConnection = topicConnectionFactory.createTopicConnection();
topicSession = topicConnection.createTopicSession(false, Session.AUTO_ACKNOWLEDGE);
topicPublisher = topicSession.createPublisher(topic);
topicPublisher.setTimeToLive(10L * 60L * 1000L);
objectMessage = topicSession.createObjectMessage();
Then I make multiple calls to :
When profiling the memory usage of my application, I noticed that for every call to topicPublisher.publish() I get a new instance of JVMClientIL & JVMClientILService created.
after sending 10,000 messages I have 10,000 of these Objects in memory. After sending ~60,000 message the VM blows up with an OutOfMemoryError (max heap set to 128mb).
It doesn't seem to matter whether I attach a Subscriber to the Topic or not, the same thing still happens.
I'm a bit of a JMS novice, so I can't see if the problem lies in the way I am using/configuring JMS, or in the implementation - I suspect it's my fault... Does anyone have any idea why this may be happening?
Thanks a lot,
Max/High memory mark.
