Michael - Can you run a STATSPACK report or otherwise get a query of the wait statistics? Once you have that, you'll know where to go.

I suspect it is the "error" of having a **HUGE** value in db_block_buffers and it's constantly crunching memory trying to figure out which ones to free up. It's only 256 meg, but depending on load, it may be too much. SGA is 687 meg. While I've got hundreds of SQL, I'm not sure I have one to diagnose buffer utilization. It's also version 8.1.7 and I could probably do some tweaking of buffers. It's Oracle CRM with a lot of customization and I'm also finding some SQL that's getting a bit ugly under there.
