Claudio Corsi commented on AMQ-3487:
------------------------------------

Thomas, can you re-run the leak and generate two or more heap dumps from that run.   Where one is generated during the beginning of the run and one at the end of the run. 

Attaching those heap dumps to this issue might allow us to determine the leak culprit.

>          Issue Type: Bug
>          Components: Broker
>    Affects Versions: 5.4.2
>         Environment: Glassfish 3.1

> We have Glassfish sending messages to an activeMQ topic using an XA Transaction. This seems to work correctly when transactions are committing.
> However, *every* time we have a transaction rollback we have a slight memory leak from activeMQ. After 1000 rollbacks our 1mb queue memory is full.

> So no obvious issue in ActiveMQ. Also, this does not happen when we use a queue and the transaction is rolled back.
> This is a serious problem for us as we are needing to restart activeMQ on a daily basis to keep the production servers running.
