This is bizarre. I have 3 servers running 5.2.0-SNAPSHOT from today. Their configuration is identical other than the broker name and broker URLs in the activemq.xml file. On two on them activemq-admin works flawlessly, on the 3rd, it sits there for 5+ minutes before returning a connection timed out for an IP address that's the external network transport the others brokers connect to, but that should have nothing to do with JMX.
iptables shows only 1099 traffic to localhost, nothing to that IP. In addition, it takes some 5 minutes to start the ManagementContext connector, which is completely at odds with what the other servers are doing. (Startup scroll pasted below with ip/host information masked) Has anybody run into a slow starting and/or non-responsive JMX connector before? The localhost:8161/admin webapp works just fine, but I'm not able to use activemq-admin at all. -D [EMAIL PROTECTED] /var/log $ sudo cat /usr/local/activemq/data/activemq.log 2008-08-05 13:46:12,665 [main ] INFO BrokerService - Using Persistence Adapter: AMQPersistenceAdapter(/usr/local/activemq/data) 2008-08-05 13:46:12,671 [main ] INFO AMQPersistenceAdapter - AMQStore starting using directory: /usr/local/activemq/data 2008-08-05 13:46:12,696 [main ] INFO KahaStore - Kaha Store using data directory /usr/local/activemq/data/kr-store/state 2008-08-05 13:46:12,722 [main ] INFO AMQPersistenceAdapter - Active data files: [] 2008-08-05 13:46:12,799 [main ] INFO BrokerService - ActiveMQ 5.2-SNAPSHOT JMS Message Broker (llarian) is starting 2008-08-05 13:46:12,799 [main ] INFO BrokerService - For help or more information please see: http://activemq.apache.org/ 2008-08-05 13:46:12,944 [main ] INFO KahaStore - Kaha Store using data directory /usr/local/activemq/data/kr-store/data 2008-08-05 13:46:12,961 [main ] INFO TransportServerThreadSupport - Listening for connections at: stomp://example.net:61613 2008-08-05 13:46:12,961 [main ] INFO TransportConnector - Connector stomp Started 2008-08-05 13:46:12,963 [main ] INFO TransportServerThreadSupport - Listening for connections at: tcp://1.2.3.4:61616 2008-08-05 13:46:12,963 [main ] INFO TransportConnector - Connector tcp://1.2.3.4:61616 Started 2008-08-05 13:46:12,964 [main ] INFO DiscoveryNetworkConnector - Establishing network connection between from vm://llarian to tcp://netresponse-test.semaphore.com:61616 2008-08-05 13:46:12,984 [main ] INFO TransportConnector - Connector vm://llarian Started 2008-08-05 13:46:13,010 [main ] INFO NetworkConnector - Network Connector nr-test Started 2008-08-05 13:46:13,010 [main ] INFO BrokerService - ActiveMQ JMS Message Broker (llarian, ID:cerberus-41952-1217969172813-0:0) started 2008-08-05 13:46:13,049 [EMAIL PROTECTED] INFO DemandForwardingBridge - Network connection between vm://llarian#0 and tcp://netresponse-test.semaphore.com/209.221.128.8:61616(netresponse-test) has been established. 2008-08-05 13:46:13,127 [main ] INFO log - Logging to org.slf4j.impl.JCLLoggerAdapter(org.mortbay.log) via org.mortbay.log.Slf4jLog 2008-08-05 13:46:13,132 [main ] INFO log - jetty-6.1.9 2008-08-05 13:46:13,525 [main ] INFO WebConsoleStarter - ActiveMQ WebConsole initialized. 2008-08-05 13:46:13,597 [main ] INFO /admin - Initializing Spring FrameworkServlet 'dispatcher' 2008-08-05 13:46:13,651 [main ] INFO log - ActiveMQ Console at http://0.0.0.0:8161/admin 2008-08-05 13:46:13,658 [main ] INFO log - Started [EMAIL PROTECTED]:8161 2008-08-05 13:49:21,814 [JMX connector ] INFO ManagementContext - JMX consoles can connect to service:jmx:rmi:///jndi/rmi://localhost:1099/jmxrmi
