Hi,<br>
<br>
I installed the latest RabbitMQ via macports on OS X 10.6.8, and have<br>
been trying to run it on localhost. However, after I started the<br>
server using 'sudo rabbitmq-server -detached', I cannot stop the<br>
server/node, nor can I start a new one (as expected). Below is the<br>
output: first, I try to start a new server but failed because there is<br>
already running; second, I then try to stop the existing server/node<br>
but get told it is already down. Can anyone point out what is going on<br>
here?!<br>

<br>
Is the existing rabbit running with the same Erlang cookie as the new one? The cookie hash produced by rabbitmqctl is for the current node, not the one you're attempting to contact.<br>
<br>
The list of nodes/ports on the given host indicates which Erlang nodes are up, but not necessarily whether they're allowed to connect to or not. Check your cookie and let us know how you get on.<span><font color="#888888"><br>
