I have seen the exact same behavior. I have actually initiated the patch for the latest amqp-1-0-client-jms library. It fixed one issue on the client but the connection still stays open on ActiveMQ.
According to Rob Godfrey (from the Qpid project) there is a potential issue in proton-c and also proton-j - the jms client is closing the connection without detaching from the session and hence the server seems to keep the connection open for a potential re-connect and resume of the session. I have not yet tested it with 5.10-SNAPSHOT which is supposed to use a proton-j-0.6-SNAPSHOT to see if it is fixed there. I can do that during the next few days and can update this post with my findings. -Uli -- View this message in context: http://activemq.2283324.n4.nabble.com/ActiveMQ-broker-5-9-doesn-t-close-TCP-connection-if-qpid-client-close-amqp-connection-tp4675756p4676002.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
