i've got 3 machines where i'm trying to cluster activemq brokers.
i can get 2 to start up just fine, but the third box starts up and says,
"Journal is already open..." then "Could not connect to local URI:
vm:?network=true"
why do 2 machines successfully link, but the third blows up?
any thoughts?
here's the relevant parts of my configuration (and the stack trace is
beneath that)
