ActiveMQ dlqDeliveryFailureCause java.lang.Throwable: duplicate from store for queue - apache

Question

I have a 3 broker setup of ActiveMQ v5.14.1. The setup involves set of composite-destinations that pulls a copy of message from another queue. Following is the configuration of one of the broker -
<broker xmlns="http://activemq.apache.org/schema/core"
brokerName="brokerC"
dataDirectory="${activemq.data}"
schedulePeriodForDestinationPurge="10000"
schedulerSupport="true">
<destinationPolicy>
<policyMap>
<policyEntries>
<policyEntry queue=">" gcInactiveDestinations="true" inactiveTimoutBeforeGC="30000" >
<deadLetterStrategy>
<sharedDeadLetterStrategy processExpired="false" />
</deadLetterStrategy>
<networkBridgeFilterFactory>
<conditionalNetworkBridgeFilterFactory replayWhenNoConsumers="true"/>
</networkBridgeFilterFactory>
</policyEntry>
<policyEntry topic=">" >
<pendingMessageLimitStrategy>
<constantPendingMessageLimitStrategy limit="1000"/>
</pendingMessageLimitStrategy>
</policyEntry>
</policyEntries>
</policyMap>
</destinationPolicy>
<!-- Added entry for network of brokers -->
<networkConnectors>
<networkConnector name="linkFromCToA"

useVirtualDestSubs="true"/>
<networkConnector name="linkFromCToB"
uri="static:(tcp://xx.xxx.xx.xxx:61616)"
useVirtualDestSubs="true"/>
</networkConnectors>
<managementContext>
<managementContext createConnector="false"/>
</managementContext>

<!-- destroy the spring context on shutdown to stop jetty -->
<shutdownHooks>
<bean xmlns="http://www.springframework.org/schema/beans" class="org.apache.activemq.hooks.SpringContextHook" />
</shutdownHooks>
<destinationInterceptors>
<virtualDestinationInterceptor>
<virtualDestinations>
<compositeQueue name="Q.1" forwardOnly="false">
<forwardTo>
<queue physicalName="Q.2" />
</forwardTo>
</compositeQueue>
</virtualDestinations>
</virtualDestinationInterceptor>
</destinationInterceptors>
</broker>
These configurations are similar on all 3 of the brokers (of course except the broker url's). On dlq of all 3 brokers after some time i see the following exception -
java.lang.Throwable: duplicate from store for queue://Q.2
This exception is in the header 'dlqDeliveryFailureCause' of the message sitting in dlq. I observed that in 1 broker setup this issue never comes up. It is only when I have 2 or more network of brokers setup.

Answer 1

For anyone getting stuck on this issue, have a look at the following link
ActiveMQ User discussion.
Two suggestions 1. disable audit at queue level and 2. change messageTTL=2 (coz i have 3 brokers).
