Who would have guessed that zombies were related to OS choice.

I have had 2 2-pacs for about 3 months. No amount of playing with voltage would stop one or both from zombie'ing out every 7 hours or so.
2 weeks ago I wiped windows 10 from my machine and installed ubuntu. The first thing I did was git and build cgminer and start them back up.
They have been running for 11 days now without a stop. I never would have guessed.
