Memory usage jumps > 100% with durable subscription and stays there
-------------------------------------------------------------------

                 Key: AMQ-1061
                 URL: https://issues.apache.org/activemq/browse/AMQ-1061
             Project: ActiveMQ
          Issue Type: Bug
    Affects Versions: 4.2.0
         Environment: Windows XP Professional, JVM 1.5.0_09
            Reporter: jk@penguinsfan.com
            Priority: Critical
             Fix For: 4.2.0


Using the store pending cursor, activemq.xml configured to use 200M of RAM and Kaha store.
 JVM started with options -Xms512M -Xmx512M -Xmn100M.  Messages are 10KB in size, prefetch
is default. 

I am seeing the memory usage immediately jump up really high (>100) as soon as a durable
consumer is activated when a large number of messages are waiting for that consumer. 

The producer hangs under this situation. 

If the consumer is killed before memory usage drops to normal, memory usage does not drop
(i.e., the server locks forever).

Sometimes, it is possible to exhaust the Java heap and actually crash the server.

Here is the kind of things I'm seeing in the DEBUG log:
