hard to tell if they were the same issues I was seeing without the full
backtrace. 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.
