Sorry, forgot to add logfile stuff... These hangups are often accompanied or preceded by log entries like:
2014-01-16 17:45:02,816 | WARN | TopicSubscription: consumer=B->A-35971-1389919240382-4:3:1:1, destinations=23, dispatched=1000, delivered=0, matched=1001, discarded=0: has twice its prefetch limit pending, without an ack; it appears to be slow | org.apache.activemq.broker.region.TopicSubscription | ActiveMQ NIO Worker 94 But the network connectors always continue to appear open in jconsole I'm suspecting this has something to do with the buffers filling up and not having space for an ack to be sent before the message can be consumed but it's only a theory -- View this message in context: http://activemq.2283324.n4.nabble.com/TCP-send-and-receive-buffers-filling-preventing-openwire-communication-tp4676493p4676495.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
