There doesnt seem to be a way of limiting how messages are delivered

the ActiveMQMessageConsumer.unconsumedMessages seems to fill up, all

we have this setting on the server
<destinationPolicy> <policyMap>
<policyEntries>
<policyEntry topic=">" producerFlowControl="false"
memoryLimit="10mb">
<deadLetterStrategy>
<sharedDeadLetterStrategy processExpired="false"
processNonPersistent="false" /> </deadLetterStrategy>
<!-- 10 seconds worth -->
<!-- lets force old messages to be discarded for slow
consumers -->
<pendingMessageLimitStrategy>
<constantPendingMessageLimitStrategy limit="1000"/>
</pendingMessageLimitStrategy>
</policyEntry> </policyEntries>
</policyMap>
</destinationPolicy>
is there another setting to protect against this kind of OOME

Hi Filip,
You can override how many messages are delivered to a consumer by
setting its prefetch limit - see the FAQ entry - http://activemq.apache.org/what-is-the-prefetch-limit-for.html
