Please check again. In particular...

1) make sure you have a completely standard install of rabbitmq, i.e. no 
modified startup scripts, etc

2) start both nodes

3) from each node, post the startup message from the regular rabbit log, 
*not* the startup log, including the time stamp (make sure it's the most 
recent startup message and not an earlier one). It should look something 
like this:

=INFO REPORT==== 22-Jun-2013::01:06:34 ===
node           : rabbit at i
home dir       : /home/matthias
config file(s) : (none)

log            : /tmp/rabbit at i.log
sasl log       : /tmp/rabbit at i-sasl.log
database dir   : /tmp/rabbitmq-rabbit-mnesia

4) from each node, take the value of the 'home dir' from the startup 
message and post the output of

cat <the-home-dir>/.erlang.cookie

If it turns out that the files are indeed identical and yet the reported 
hashes are different, then something seriously odd is going on. If so, 
could you give us access to these machines so we can investigate?
