A few slowdowns to even lockdowns I've noticed at a few older scripts of me is at moments when there is a high memory drop, lost of connection to a certain NAS drive, network timeouts etc.. which loads up more childs than the poor parent could support.

I've been creating an error-library only for that to keep up with such errors, best to keep code working clean is also intercepting the eventual problems in a clean way.

Be prepared coding for any error and the code will be prepared for you...

After installing the error library I've noticed no other lockups; because I was prepared, even for doom scenarios which happened once when the power supply of the NAS drive failed continuesly spawning children by the dozen ... Bugs Bunny would have been jealous that time!
