Some times my scripts starts to take lots of cpu-cycles and relaunching Finder fixes it. Finder wasnt “Not Responding”.
Does your script call the Finder? We’re going to need more detail, or even a portion of the script(s?). 
It dosnt call Finder and i have this problem in all of my scripts.
Still can’t fix anything without code.
Yeah, give us one sample that does it every time on your machine, and tell us what version of the system it happens on.
Hmm, I remember reading that System Events employs the Finder for some of its functions.
Hence, I’ll ask: does it call System Events?
