[plt-scheme] Broken pipe?

I recently had a similar bug.  Both the #<eof> and broken pipe  
suggest the server side has been closed, which would happen if the  
procedure passed to `run-server' returned or raised an exception.    
Have you tried something like this, to see if that is happening:

    (lambda (in out)
         (lambda () #f)
         (lambda () (printf "Unexpected return!~n"))
