It's actually funny you say that...
The boxes that are running best for me are the boxes that have been imaged, and upgraded since PSA 5.0.5 and RH7.2, they've moved acrossed hardware and endured OS upgrades to be the most stable in the bunch. The box in queston was migrated to a new server at my location from one of the larger facilities out west. That bow was brand spanking new with FC1 and PSA 7.1.6 at the time, and it's been nothing but a headache. It keeps me busy though, and albeit it's a pain, it's fun to play with for practice. The customers never see the turmoil on my side.
The moral of the story is. Anyone can reinstall, but why bother if you can just fix it. Uptime my friend...uptime.
I used to do the same thing, so i need to call myself a hipocrite right now, before lightning strikes me down. Re-installing is a matter of how much time you have the way I see it. There is a lesson to be learned in getting an abortion to purr like a kitten though.
I digress...
