Dee Moore commented on AMQ-3710: -------------------------------- We hit the same issue on ActiveMQ 5.14.2. It was configured to delete inactive destinations. We solved this by reviewing our topics - we were making transient topics such as /topic/topic.prefix.<uuid>.entry, which sent small amounts of data and then became inactive. However, one of our subscribers was subscribing to /topic/topic.prefix.>, and this was enough to keep every topic active, and resulted in steady growth of db.data, with only one active .log file. Even though we found a solution, it would be very nice to be able to mark a channel as "This channel is inactive when messages have not been sent for x amount of time and should be deleted, whether or not there are active subscribers". I cannot find a way to do this - having a subscriber, even on a wild card basis, is enough to keep a topic active. > Activemq broker hangs > --------------------- > > Key: AMQ-3710 > URL: https://issues.apache.org/jira/browse/AMQ-3710 > Project: ActiveMQ > Issue Type: Bug > Components: Broker > Affects Versions: 5.4.2 > Environment: cent os linux version 5, 64 bit os, java 1.6 update 21 > Reporter: Krishnadasan T S > Priority: Major > > I am using activeMQ 5.4.2 as separate process in my production. more than > 2000 topics and 600 clients are connecting to broker.
