Subject Re: ActiveMQ hangs and i don't understand why
Date Mon, 28 Mar 2016 12:34:12 GMT
For the JMX: there is a newer setting in the activemq configuration file
that may override the command-line settings; here's a fairly stock example:

        <managementContext>

            <managementContext createConnector="true"/>

        </managementContext>

Check for these and any output during broker starting indicating the
management context failed to start -- if both try to start (via command
line and the config file), typically one fails.  The following can help
track down the state of JMX as well:


   - netstat -an | grep 1616
   - netstat -an | grep LISTEN
   - ps axu | grep java

The first two will show info on the ports open for listening on the
server.  The third shows the actual command-line used to start ActiveMQ.

Note that JMX can be tricky to start behind a firewall because it tends to
allocate a second port dynamically.  Adding a line like the following to
the ACTIVEMQ_SUNJMX_START may fix that issue:

-Dcom.sun.management.jmxremote.rmi.port=1615

Then make sure the same is open through the firewall.  Note that JMX uses a
different method of connection for local processes, so it's entirely
possible that the JVM is not properly configured to allow network
connections.
