That said, I thought we'd converted that to a more intelligible error message (it could hardly be less). Which version of RabbitMQ are you running?<br>

Hello,<br>
<br>
I am trying to cluster a slave node (rabbit2) with a master node<br>
(rabbit1) in RabbitMQ. I am receiving the following error from the<br>
|join_cluster| command, though. I don't know Erlang, so I am having<br>
trouble determining the cause. Any ideas as to what the error is, or how<br>
to fix it?<br>
<br>
Both nodes can talk to each other via ping, and I have ensured that the<br>
.erlang.cookie for each node is the same.<br>
<br>
|root@rabbit2:~# rabbitmqctl stop_app<br>
root@rabbit2:~# rabbitmqctl join_cluster rabbit@rabbit1<br>
