Subject Memory usage always increasing
Date Mon, 25 Jun 2007 22:44:42 GMT


I am running an embedded ActiveMQ 4.1.1 on Jboss 4.0.3. I am doing a stress
test with the following configuration.


Threads - 3
Iterations per thread - 100000
Sleep time between iterations - 500 ms


Listener Thread - 1
Durable Topic consumer.

broker configuration:

memory limit set to 512 MB.

As the stress test is progresses, I can see the Memory percentage usage

The memory percentage used is 50% for 65000 messages. That means before 100%
of the memory is used only 130000 messages only can be consumed or would
ActiveMQ's GC will clean up the memory sometime. 

How does the ActiveMQ GC work?
