AMQ 5.0 Stable release "PS Old Gen" Memory is growing continuously
------------------------------------------------------------------

                 Key: AMQ-1662
                 URL: https://issues.apache.org/activemq/browse/AMQ-1662
             Project: ActiveMQ
          Issue Type: Bug
          Components: Broker
    Affects Versions: 5.0.0
         Environment: AMQ 5.0 RC on Solaris 8, JDK 1.5_07
            Reporter: vik dhawan


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!
