----------------------------------------------------------------------------------------------------------

                 Key: AMQ-1764
                 URL: https://issues.apache.org/activemq/browse/AMQ-1764
             Project: ActiveMQ
          Issue Type: Bug
          Components: Broker
    Affects Versions: 5.1.0
         Environment: win2003sp2 , activemq 5.10 ,jdk6.0update6
            Reporter: armgong
         Attachments: test.zip

I write a fast producer(produce a message take 1 ms) and a slow consumer(consumer a message
take 10 seconds) application,and config standalone activemq through activemq.xml,in the activemq.xml
I config constantPendingMessageLimitStrategy limit="10",and in the slow consumer i config
connection url is "tcp://127.0.0.1:61616?jms.prefetchPolicy.queuePrefetch=50".
 but the strange problem happends when i want send 200k 512 bytes size messages to borker
through fast producer. 
when producer send  messages start,the borker and the slow consumer memory useage grow very
fast,after send 120k messages, the slow consumer take 80MB memory from at application start
18MB memory,and borker take 140MB memory, then borker slowing down,and totaly freeze.
