I think I am not using flowcontrol. I´m using 5.3. The broker is not receiving messages any more and producers are stopped but no error is thrown. Also when I try to inspect that queue with jconsole, jconsole also hangs displaying only a gray screen. CPU and RAM seems to be ok. This is my configuration: <broker xmlns="http://activemq.apache.org/schema/core"; brokerName="localhost" dataDirectory="/data/activemq53/" useJmx="true" advisorySupport="false" useShutdownHook="true"> <plugins> <statisticsBrokerPlugin/> </plugins> <!-- Destination specific policies using destination names or wildcards --> <destinationPolicy> <policyMap> <policyEntries> <policyEntry queue=">" producerFlowControl="false"> <pendingQueuePolicy> <fileQueueCursor /> </pendingQueuePolicy> </policyEntry> <policyEntry topic=">" producerFlowControl="false"> <dispatchPolicy> <strictOrderDispatchPolicy/> </dispatchPolicy> <subscriptionRecoveryPolicy> <lastImageSubscriptionRecoveryPolicy/> </subscriptionRecoveryPolicy> </policyEntry> </policyEntries> </policyMap> </destinationPolicy> <destinationInterceptors> <virtualDestinationInterceptor> <virtualDestinations> <compositeQueue name="EVENTS.A"> <forwardTo> <queue physicalName="EVENTS.A.STATISTICS" /> <queue physicalName="EVENTS.A.WAREHOUSE" /> </forwardTo> </compositeQueue> </virtualDestinations> </virtualDestinationInterceptor> </destinationInterceptors> <persistenceAdapter> <kahaDB directory="/data/activemq53/kahadb" enableIndexWriteAsync="true" journalMaxFileLength="20mb"/> </persistenceAdapter> <systemUsage> <systemUsage sendFailIfNoSpace="true"> <memoryUsage> <memoryUsage limit="100 mb"/> </memoryUsage> <storeUsage> <storeUsage limit="80 gb" name="foo"/> </storeUsage> <tempUsage> <tempUsage limit="1 gb"/> </tempUsage> </systemUsage> </systemUsage> <transportConnectors> <transportConnector name="openwire" uri="tcp://0.0.0.0:61616"/> </transportConnectors> </broker> Thanks -- View this message in context: http://old.nabble.com/Broker-hangs-and-cant-restart-it-tp28337031p28341513.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
