Alright, I'm confused. In your earlier post you said the stop script is 
not running. Yet here it is, just not at the right time. I think a more 
detailed explanation is needed:

1) The stop script you are concerned about is a systemd  script, one 
that you created or system provided?

2) What is the shutdown service you refer to?

3) Is there a separate shutdown script for the Control-M product?

4) What do you expect to happen vs what is happening?
