Hi All,

I am having issues getting a 3 node cluster to work. I am able to
cluster any combination of the 3 nodes with each other however when i
try to join the third node into the cluster it keeps telling me that
"Mnesia could not connect to some nodes".

All nodes can ping each other, I can see the status of all nodes from
each other when running sudo rabbitmqctl -n <node> status, all share
the same cookie and all the host file entries are correct. Is there
anything extra that I need to allow 3 nodes to be clustered.

I am running three ubuntu vm's on a win 7 desktop, I setup the first
vm and cloned the other two from it then changed hostnames etc.
RabbitMQ version 2.7.0 and erlang R14B02

Any thoughts would be welcomed and be gentle as I am a linux novice.
