When running multiple brokers on the same box, "activemq-admin stop" command on a downed instance
will shutdown other instances
-------------------------------------------------------------------------------------------------------------------------------

                 Key: AMQ-2814
                 URL: https://issues.apache.org/activemq/browse/AMQ-2814
             Project: ActiveMQ
          Issue Type: Bug
          Components: Broker
    Affects Versions: 5.3.0
         Environment: Linux 2.6.31-22-generic-pae #60-Ubuntu SMP Thu May 27 01:40:15 UTC 2010
i686 GNU/Linux

            Reporter: Scott Emmons
            Priority: Critical


In an environment where multiple ActiveMQ broker servers are running on the same host, the
"activemq-admin stop" command will shutdown other instances if the requested instance is already
down.

This is very dangerous behavior in the case where a user inadvertently attempts to shutdown
a broker instance which is already down - instead of getting an error message, or the command
being a no-op, a different instance than requested will be shutdown instead.

To reproduce:

* Install ActiveMQ into SOMEDIR/broker_a and configure port and name.
* Install ActiveMQ into SOMEDIR/broker_b and configure unique port and name.
* Start broker_a - broker_a/bin/activemq (or alternatively activemq-admin start)
* Start broker_b - broker_b/bin/activemq (or alternatively activemq-admin start)
* Stop broker_a - broker_a/bin/activemq-admin stop
* Try to stop broker_a again - broker_a/bin/activemq-admin stop -- THIS WILL RESULT IN broker_b
SHUTTING DOWN

If there are three or more instances, the result is the same - "activemq-admin stop" will
shutdown instances other than the one requested.
