Had a really nasty problem today:
Attempt to fetch logical page (1:181882) in database 'prodNextGen' belongs to object '893596208', not to object 'AssignmentOwner'.
The only time I'd seen that before was when a server had lost power mid-write. Fortunately, it appears to be an isolated-to-one-table problem, and since the server didn't lose power it's probably a bug in SQL Server. But I'm not reporting it to PSS because it happened on my production server, and I don't have time to deal with PSS, and I think we caught it before it went into a backup. I had a minute...
