>             Project: ActiveMQ
>          Issue Type: Bug
>          Components: Broker
>    Affects Versions: 5.0.0
>         Environment: AMQ 5.0 RC on Solaris 8, JDK 1.5_07

>             Fix For: NEEDS_REVIEWED
> When AMQ runs for couple of days and there is lot of message traffic, PS Old Gen memory
pool keeps on growing. i have tried fine tuning JVM options for GC but no help. 
> what i realize is when i hit purge on the queues using JMX then PS Old Gen goes down
again, even if there are no messages in the AMQ all the produced messages are consumed. 
> in my last posting i got response from a fellow AMQ member that in 5.0 it cleans the
messages after the old message count reaches 1000Message or something, but that doesn't appear
to be working here. 
> this scenario makes me believe that there is some relationship between the old message
cleanup and "PS Old Gen" size increase. 
> Thanks!
