I can now reliably reproduce the problem on a Leopard machine at our 
offices, running on a ppc platform with Erlang R12B-0 from macports and 
the latest development snapshot of rabbit.

The results indicate that this is probably a bug in Leopard, or a bug in 
the Erlang runtime that only manifests itself on Leopard.

The trigger appears to be a tcp client closing the socket when the 
server is in the middle of writing to its peer.

The next step is to construct a test case that doesn't involve rabbit.

Matthias.
