That shows that there is a rabbit running. Unless it died w/o epmd 
noticing, which is not something I've see before.

To find out the process, use 'lsof' and look for the port number of the 
rabbit node (33213 in this case), e.g.

   lsof -n -iTCP | grep 33213

NB: you may have to be root to do this, otherwise not all processes may 
show up.
