Thank you Tim, activemq version 5.12.3
it is our own code. dynamically using UI we are creating n/w connector. at that time below code execute. code snippet : NetworkConnector networkConnector = new DiscoveryNetworkConnector(uri); networkConnector.setNetworkTTL(this.networkTTL); networkConnector.setBrokerURL(server.getUrl()); also jprofiler is using 'subscriptions' word even on queue. So queue's subscriptions showing as zero. but in logs no where finding any information on closing subscriptions. one information we are finding as warning : Network connection between vm://jcs-broker#7832 and HTTP Reader https://A:22002 shutdown due to a remote error: javax.jms.InvalidClientIDException: Broker: jcs-broker - Client: replication_3002_A_localhost_outbound already connected from blockingQueue_432061146 exact error of losing connection not finding, even closing subscription also not finding. however using jprofiler when we are looking difference between A,C then we are finding A has 2 subscriptions with B & C where as C has only 0 subscriptions. -- Sent from: http://activemq.2283324.n4.nabble.com/ActiveMQ-User-f2341805.html
