Subject: Rollback waiting on 'cache buffer chains' latch

Hi List,  

I've got a production database that currently has a terminated session stuck in the rollback state and v$session_wait shows it is waiting on 'latch free' for the 'cache buffer chains' latch. This hung session is holding several locks that are blocking other users so I'd like to get it cleared out ASAP, but I'm not sure how to do that. V$transaction only shows 69 for used_ublk and it's not changing. I've already opened an SR and am awaiting Oracle's response and also still researching & troubleshooting on my own, but thought I'd see if any of you folks have an answer or any suggestions.  

Thanks,
Brandon
