Hi, I have two ActiveMQ 5.8 instances setup in a network of brokers. Each instance is hosted on a separate machine running Ubuntu 12.04 with 8GB of memory. After one week in production, we started seeing consumers that wouldn't accept messages. In the web console I can see the messages enqueue and messages in the dispatch queue, but the messages are never consumed in the server application. Restarting the consumer doesn't fix the problem. When I tried restarting the ActiveMQ instance it failed to shutdown -- needed to kill -9 the pid.
I believe the problem is on the broker or in the CMS library, but I can't seem to track it down. Has anyone seen a problem like this before? =================================================================== Application topology, request/response pattern w/temp queues, not persistent: ASP.NET/NMS <-- producer (x350) --> ActiveMQ 5.8 (x2) <-- consumer (x120) --> C++/CMS Win2003/IIS6 Ubuntu 12.04/OpenJDK 7 Ubuntu 12.04 =================================================================== Portions of activemq.xml: <amq:policyEntry queue=">" optimizedDispatch="true" lazyDispatch="false" producerFlowControl="false" strictOrderDispatch="false"> <amq:deadLetterStrategy> <amq:individualDeadLetterStrategy queuePrefix="DLQ." useQueueForQueueMessages="true" /> </amq:deadLetterStrategy> <amq:dispatchPolicy> <amq:roundRobinDispatchPolicy /> </amq:dispatchPolicy> <amq:messageGroupMapFactory> <amq:simpleMessageGroupMapFactory /> </amq:messageGroupMapFactory> <amq:pendingQueuePolicy> <amq:vmQueueCursor /> </amq:pendingQueuePolicy> </amq:policyEntry> <amq:memoryUsage> <amq:memoryUsage limit="64 mb"/> </amq:memoryUsage> <amq:storeUsage> <amq:storeUsage limit="100 gb"/> </amq:storeUsage> <amq:tempUsage> <amq:tempUsage limit="50 gb"/> </amq:tempUsage> =================================================================== JVM memory: ACTIVEMQ_OPTS_MEMORY="-Xms4G -Xmx4G" Thanks, Dave -- View this message in context: http://activemq.2283324.n4.nabble.com/ActiveMQ-consumers-stop-accepting-messages-tp4678923.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
