I could not understand Why ActiveMQ is consuming and increasing its Memory
usage, when there is no activity on queues.

It seems no GC thread running in ActiveMQ, because when ever I am running
Perform GC in JConsole the graph drops down immediately.

Please look into attachments, in ActiveMQMemory.JPG file please observe the
vertical straight line of memory usage WHEN THERE IS NO ACTIVITY ON QUEUES
i.e no producer or consumer are working, though there are some persisted
messages were there.

Environment: ActiveMQ 5.2.0 / Windows 2003 server / Oracle 10g / TCP
openwire / JVM 512 MB.


Please look into attachment / Please Help Me.

Thank You,
Nag.
