FYI, I tried downgrading to 3.8-rc4-raring, and the problem was still reproducible.
Comparing notes with other folks who have similar setups and are not seeing this problem, my attention was drawn to the fact that I had /tmp on a tmpfs. I thought the tmpfs was probably not the problem, because I had tried size limiting it and was still seeing problems. However, after disabling use of tmpfs for /tmp six days ago (which probably no longer makes sense for my environment now that I have an SSD), the problem has not recurred, even though my usage pattern hasn't changed. I have seen instances where firefox has managed to be killed due to OOM, but I have not seen swap death with 80% of swap unused like I was seeing before. So it seems likely that this is related to use of tmpfs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1152736 Title: system swapping itself to death in raring for no good reason To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1152736/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
