And when it hangs, what happens if you telnet to the server (port 119)? 
  What if you try running `ctlinnd mode`?

I've never seen this before, but it sounds a little bit like there's 
something wrong with the .pid files stored in PATHRUN, almost as if the 
shutdown script is seeing the wrong PIDs when it looks.

If you look there just before trying to restart, are the PIDs in and the same as you see in `ps`?

I haven't tried.

I'm still a little puzzled by the fact that it doesn't happen when you 
run the stop/start commands manually, though.  (You've tried that 
enough times to know it's not coincidence?)
