The only bad rss bugs that I recall being fixed for sure were the ones that Hugh nailed down right before 3.14 (887843961c4b) I've not seen anything in a while, but that may just be because I end up hitting other bugs before they get a chance to show. Brandon, what kind of workload is that machine doing ? I wonder if I can add something to trinity to make it provoke it.
