Once upon a time there was a major German online service provider (I refuse calling this kind of service ISP) who ran their accounting database on a faily new fairly big Sun E10K with lots of online storage behind it (millions of accounting records per day take some space). Only after recycling the oldest backup tapes someone noticed complete database corruption - caused by a broken SCSI driver writing nonesense to the disk. So much about "serious production quality OS"es. The only OS without any serious problems of this kind I've ever had was Tandem's Nonstop kernel and I'm sure I was just lucky. Noses.
