I would like to add that depending on what the server is doing can determine 
the best way to attack your problem.  I have had web servers go crazy at 
some point (my server has been /.'d (slashdot.com) once or twice) and 
pulling the network cable will allow my apache processes to time out and 
start dying off.  After a few minutes, I can su and do a reboot (or 
whatever.) It doesn't quite "fix" the initial problem, but does allow me to 
enough CPU / resources to start the shutdown process.

Just my $.02 from experience.
