I experience the same on desktop (15.04) maybe once a week. I presume that this happens when some laking application starts to eat up all the memory quickly. When this happens the whole machine gets unresponsive immediately and only restarting helps. It only turns out from the atop logs what happened after the machine was restarted. Atop is configured to run every 30 secs. It is visible from the atop logs that kswapd0 is eating up all the cpu resources. Strange thing is that this happens despite there is no swap enabled.
I suppose what should happen is that the kernel OOMs and kills some application and everything is back to normal. What happens though is that the machine dies. Of course every unsaved work and open windows and applications are lost, which is very unfortunate. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1462919 Title: kswapd pulls server down every 2 weeks.
