I am running and ActiveMQ broker within JBoss. I have a Spring client which uses JMSTemplate/DefaultMessageListenerContainer to consume messages from 7 queues. When I bring up the client consumers, they run great for an hour or 2 and then they don't seem to receive any messages from the queues, though messages keep piling up in the queue. I see these messages which say that they are listening but not getting any messages

08:22:46.140 DEBUG[listenerContainer-2] [ ] [msg:] listener.DefaultMessageListenerContainer - Consumer [com.stc.jms.client.STCQueueReceiver@ae1cf] of session [com.stc.jms.client.STCSession@6ef7ba] did not receive a message
