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

    Eric Zhao Newbie

      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.
