Well, "cfengine-die" works for me in a production environment.  What
version of cfengine are you using (I use 1.6.2 and .3)?  Can you post
the script itself, or at least the relevant parts?  Have you tried the
useshell option?

Take a look at

http://www.cfengine.org/docs/cfengine-1.6.3.Reference.html#processes

and you'll see the explanation of why non-forking daemons don't work
too well with cfengine 1.6.3 and earlier.  I don't know about the 2.0
releases, as I haven't had the time to test them in our environment.
>From the 2.0 documentation on the web site, it doesn't look like the
current 2.0 release is very different in regards to non-forking
daemons.

Thanks
Ted
