> 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 this many rollback() operations, 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.
> session.commit() operations (x thousands and more) do not lead to a leak
> we do not use XA.
> thanks for your help.
