To solve this problem you can add 'kill timeout 30' to pref.conf, this 
basically tells upstart that a process may take up to 30 seconds to exit after 
SIGTERM, and only if it doesn't exit after that it will send SIGKILL.

But as for the issue of why upstart is not picking up the PID correctly, I'm 
not sure yet.  I'm actually dealing with similar issue now so I'll post more 
when I find something.

BTW, just noticed you're using su -c to run the program.  I think this spawns 
a shell which may be the cause.  Could you add 'expect fork' to pref.conf and 
see if it changes anything?
