Replying to my own post now months later. We successfully had 5.11.0 running for over 136 days until we decided to do some maintenance and reboot the server this morning.
Now first problem, is again we couldn't get the lock. The consumers would connect but could not enqueue messages. I will attach the log file. activemq.log-old <http://activemq.2283324.n4.nabble.com/file/n4698488/activemq.log-old> So I moved the old directory then extracted a fresh copy from apache-activemq-5.11.0-bin.tar.gz and tried to start. Again there was a problem attaining lock. Deleted the lock file and the suddenly the connections could send messages ! The problem I'm seeing now is that the broker tries to start another service but cannot due to the existing process. activemq.log-new <http://activemq.2283324.n4.nabble.com/file/n4698488/activemq.log-new> Is this a bug or what ? -- View this message in context: http://activemq.2283324.n4.nabble.com/kahadb-lock-in-logs-tp4691746p4698488.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
