Timothy Bish commented on AMQ-3710:
-----------------------------------
First suggestion is to upgrade to the latest Apache release v5.5.1 or try a
SNAPSHOT build of 5.6 as there have been numerous bug fixes. Otherwise we'd
need more to go on like your broker configuration and logs from the broker with
debug tracing on.
