Hi The symptoms of our configuration got more and more weird. We use currently topics where we have up to 5 producers and about the same number of consumers, mostly spread over the two boxes having a broker each. We did a run overnight and it ended with one broker falling over with not enough memory (our fault)) but the other one is in a very inconsistent state. It doesn't accept incoming connections from the other box (the clients are configured to try first the local then the other broker) and I can see very high numbers of subscribers on one of the topics (a value of up to 4 would make sense but JMX currently shows 314 - sometimes the value goes up to above 3000 for a second). the clients on the remote box loop in message like:
INFO [02 Feb 2012 21:33:36,855]: Successfully reconnected to tcp://otherbox:61616 WARN [02 Feb 2012 21:33:36,855]: Transport (otherbox/10.100.88.17:61616) failed to tcp://kd-sage3:61616 , attempting to automatically reconnect due to: java.net.SocketException: Socket closed On the broker side I got: 2012-02-02 21:33:36,858 | INFO | Transport failed: java.io.EOFException | org.apache.activemq.broker.TransportConnection.Transport | ActiveMQ Transport: tcp:///10.100.88.16:36006 2012-02-02 21:33:36,914 | INFO | Transport failed: java.net.SocketException: Broken pipe | org.apache.activemq.broker.TransportConnection.Transport | Async Exception Handler We use a Spring connection factory to connect, which is set to reconnect automatically if connection is lost: @Bean public CachingConnectionFactory cachingConnectionFactory() { CachingConnectionFactory factory = new CachingConnectionFactory(); factory.setReconnectOnException(true); factory.setTargetConnectionFactory(jmsConnectionFactory()); return factory; } @Bean public ActiveMQConnectionFactory jmsConnectionFactory() { ActiveMQConnectionFactory factory = new ActiveMQConnectionFactory(); factory.setBrokerURL("failover:(tcp://localhost:61616,tcp://otherbox:61616)?randomize=false"); return factory; } The only solution we found was to restart the broker, but as this stuff is planned to go into production we want to serve them a configuration that can have the broker running for months without need to interfere with it.
