exiting with badarg && Erlang Web server

[Francesco Cesarini]

The only bad arg I can see occur here (You unfortunately provided too
little of the code) is if you are attempting to send a message to a
registered process which does not exist. 

* Has chat_server been started, and has the process been registered? 
* If you have spawned a process, has it crashed? (These suckers tend to
die silently.) 

Check it out by using the BIF registered().

Eddie is the fault tollerant distributed web server. You can download it
from http://www.eddieware.org
