------------------------------------------------------
it seems https://issues.apache.org/activemq/browse/AMQ-1136
btw the attach file is includes the activemq config file activemq.xml and producer (in producer dir )and slow consumer application (in slow dir). the two applications user none_durable topic "chatTopic.chatMessage"
if configured in activemq as following :
<destinations>
<topic physicalName="chatTopic.chatMessage" />
</destinations>
<!-- Destination specific policies using destination names or wildcards -->
<destinationPolicy>
<policyMap>
<policyEntries>
<policyEntry queue=">" memoryLimit="20mb"/>
<policyEntry topic="chatTopic.chatMessage" memoryLimit="64mb">
<dispatchPolicy>
<strictOrderDispatchPolicy/>
</dispatchPolicy>
<subscriptionRecoveryPolicy>
<lastImageSubscriptionRecoveryPolicy/>
</subscriptionRecoveryPolicy>
<!--slow consumer policy-->
<pendingMessageLimitStrategy>
<constantPendingMessageLimitStrategy limit="10"/>
</pendingMessageLimitStrategy>
</policyEntry>
</policyEntries>
</policyMap>
</destinationPolicy>

> 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.
