Actually, as it turns out the nohup'd processes are all owned by root, 
so changing to "no" didn't fix, but it's my understanding that if the 
setting isn't set root is always excluded anyhow.  Out of the 18 
processes that are running, my script only sees 6 of them.  Again, it's 
just doing a "ps -ef" to a file.  All 18 processes exist prior to 
shutdown and the script shows that if I run  manually.
