Yes, this is very unreasonable for a table this size; especially the 4 gig rollback when the table was empty to begin with.

That was my original thought, and that might still be the case, but v$session_longops and v$sort_usage didn't support that theory. But I might have checked at the wrong time, and what was seen at the time I checked was just an innocent bystander who happened to be in the wrong place at the wrong time. The Ouija board and Magic 8 Ball were consulted, but results were inconclusive.

I'm thinking you got some rotten SQL running around. Mebbe a Cartesian join or two. Mebbe some batch jobs in dire need of commit here and there. Seriously. Really. This should not be happening.

Don't have that many. It varies between 60 - 80 Oracle test and development databases depending on what is going on. Everybody likes to have their own sandbox, and we're just fabulously nice guys around here. Don't know how many SQL Server instances are around. Besides I just work here. I get paid. I'm happy.
