RE: java heap space

[Amy Hartland (DHCW - Integration Services)]

Hello, 

         <pendingMessageLimitStrategy>
                    <constantPendingMessageLimitStrategy limit="5000"/>
                  </pendingMessageLimitStrategy>
                </policyEntry>
              </policyEntries>
            </policyMap>
        </destinationPolicy>

I increased the pending message limit strategy from 1000 to 5000...

So far this has helped, no further heap space errrors. 


JVM config; 

# Initial Java Heap Size (in MB)
#wrapper.java.initmemory=3

# Maximum Java Heap Size (in MB)
wrapper.java.maxmemory=1024

Thanks,
Amy

Hi,

can you share your JVM configuration and your activemq.xml config file?

Regards,
