jboss messaging / memory leak on session.rollback() operation
-------------------------------------------------------------

                 Key: JBMESSAGING-1685
                 URL: https://jira.jboss.org/jira/browse/JBMESSAGING-1685
             Project: JBoss Messaging
          Issue Type: Bug
          Components: Messaging Core
    Affects Versions: 1.4.3.GA
         Environment: Windows Server 2003/SP2
            Reporter: Martin Gysel
            Assignee: Tim Fox
             Fix For: 1.4.3.GA


we run a transacted jms application using jboss 5.1.0.GA and jboss messaging 1.4.3.GA. if a received message could not be successfully processed, e.g. because another subsystem is not available, the application issues a rollback() operation on the session. by default it is presented again 10 times until it is discarded/removed. as the jms workload is quite high sooner or later the application server ends up in out of memory conditions in heap space.

the case can easily be reproduced with a small test application (one program sending messages, the other one receiving). the following cases/setups have been tested and ran into this memory leak
- close session/connection after so many rollback() operation, e.g. 100
- close session/connection after all messages have been received (and removed)
- clustered vs. not clustered makes no difference
- hypersonic vs. db2 makes no difference
- adding a DLQ makes no difference
- DeliveryMode.NON_PERSISTENT makes no difference

the same problem can also be seen with jboss 4.2.3.GA and jboss messaging 1.4.2.GA.
we do not use XA.

thanks for your help.
