[rabbitmq-discuss] Can't get rabbitMQ to restart after switching machines -- some kind of DB error...?

Tue Dec 6 15:34:32 GMT 2011

I'm running a django/celery app on EC2, with rabbitmq as the broker. The machine
I was using failed, so I fired up another instance. But since switching to the
new machine, I haven't been able to get rabbitmq-server to start up.

Here's the output:

$ sudo rabbitmq-server start

Crash dump was written to: erl_crash.dump
init terminating in do_boot ()

There's also an erlang daemon process running in the background.  I'm not sure
if this is important or not.

$ ps aux | grep rabbit

Any ideas on how to further diagnose/solve this problem?

Thanks in advance!
