In my case(windows), 1. I just ran the stop service. 2. The started the service.

In my case under Ubuntu 11.10 it helped to

#rabbitmqctl cluster MASTER SLAVE
#rabbitmqctl start_app

before I always got this error message...

Answer 3

The rabbitmq server was running somewhere but it just couldn't be connected to.

One of the following will mention something about rabbits:

$: ps aux | grep epmd
$: ps aux | grep erl

Kill the process with kill -9 {pid of rabbitmq process}
