hornetq question - there are huge number of ServerMessageImpl in jmap dump

Hi,

I got one out of memory (heap space) in jboss 6.1.0 Final version, after doing jmap, I found there are > 65,000 count org.hornetq.core.server.impl.MessageReferenceImpl and ServerMessageImpl.

checking the code, we set the auto acknowledgement when createSession:

topicSession = topicConnection.createSession(transacted,ackMode); // AUTO ACKNOWLEDGE

we didn't set the following in hortnetq-jms.xml since we think it's already AUTO-ACKNOWLEDGE.

<pre-acknowledge>true</pre-acknowledge>

I don't know in which case/scenarios the ServerMessage and MessageReference object live in the memory?

can someone help me out?

Thanks a lot.

Eric.
