In my experience Windows can run very reliably (uptime >>1 year) if you have proper hardware. Can and usually does are not the same. I would bet that i can run XP for 1 year at a crack so long as i do not do nay updates (which always require a reboot). In linux i have done nearly a year, but power failure got in the way, and i could keep the system completely up to date.

Kind of a clue that some serious things were let to just slide. If i managed a $100 million rig and there was some sloppy and safety critical software like that, the programmer would be on the rig troubleshooting it 24/7. And maybe his boss to boot.

But the software met specifications. Perhaps the team that wrote the specifications should be strung up instead.
