[rabbitmq-discuss] Clustering on Same Machine

Sat Feb 5 22:13:26 GMT 2011

Hi Max,

That might be caused by stale mnesia databases in /var/lib/rabbitmq.

Could you try to clean that directory (rm -rf /var/lib/rabbitmq/* should
be enough) and try again?

Note that this will remove any messages, queues, etc. from that machine.

Cheers,
Alex
