We've seen this error before on systems that either had an ancient or 
broken Erlang installation (e.g. a newer installation had been copied 
over an old one), and/or where tests were run that used up all file 
descriptors.

Does any of that ring a bell?

In any case I suggest you

1) eradicate your Erlang installation (which is R14B04 and pretty old) 
completely

2) install the most recent Erlang release (R16B01). There have been 
fixes around port/fd usage, which may well eradicate the problem you are 
seeing

3) switch from rabbitmq 3.0.4 to the latest (3.1.3). There have been a 
number of improvements in the area of the above crash.


Also, for reference, please let us know what OS & version you are running.

Matthias.
