Subject exception trying to stop activemq, stomp weirdness
Date Tue, 28 Sep 2010 20:26:39 GMT

I'm on Red Hat Enterprise Linux 5, in case that matters.  ActiveMQ 5.4.0 is
installed to /usr/local/activemq, and a user named 'activemq' owns this
directory and everything in it (via `chown -R activemq
/usr/local/activemq`).  The behavior described here happens when I take the
actions described either as 'root' or as 'activemq'.

If I say `activemq start`, I get a java process running and `netstat -a`
shows port 61616 being used.  `activemq stop` throws a Java exception, then
terminates ActiveMQ with SIGKILL:

$ bin/activemq stop

/home/activemq/.activemqrc)

INFO: Regular shutdown not successful,  sending SIGKILL to process with pid
'6206'

This is acceptable, but obviously less than desirable.  What might be
causing this?
