erlang/rmq is notoriously brittle if the hostname being used
('controller') does not forward and reverse resolve on the host its
running on (and all other hosts that you might want to cluster it with).

Please check this is the case:

  sudo nslookup controller

Marking 'Incomplete'; if the hostname controller does not
forward/reverse lookup between hostname and IP OK then please fix that
and mark this bug as Invalid; otherwise please comment and set back to
'New'.
