You think I might have problems with this? My plan is that this script would only be run like 50 times a week
I don't know for sure whether you would have problems, or not, as I don't know what the script *does*, how "efficient" it is, etc. My warning was just so that you would consider the issue. I *will* say that if the script significantly loads the server "several" times a week, DH would be correct in preventing it's use on a *shared* server.
At the very least, I would suggest, if you use such a script, that you carefully target when it is run to be at a very "low load" time when fewer users are likely to be impacted. Actually, I would run it past DH support first, as there are certain other issues involved; by setting your execution time so high, you risk any "runaway" script running as your user to *also* risk overloading the server.
Those are just my thoughts, and I *am not* a DH employee, so please remember that YMMV
