Raising /proc/sys/vm/min_free_kbytes from about 65000 to 200000 KiB helped here on a ThinkPad T520 equipped with a 8 MiB for RAM. I now have the oom killer raised while Planeshift client was doing accesses to BTRFS. Thus I have a complete OOM backtrace and I bet thats likely the place where before BTRFS crashed the kernel before the OOM killer could chime in to clear up the situation. The rtkit-daemon invoked the OOM killer, since I do not use Pulseaudio anymore since it didn´t work to my satisfaction on this machine as well, I might remove it. But then someone else will likely trigger it. :) If need be, I would reduce the min_free_kbytes again until it crashes some more time and do a screenshot, but a screenshot always only just shows part of the trace. Some my memory the backtrace I saw on tty1 was similar to the psclient.bin backtrace in the following OOM excerpt. Otherwise I will leave it at that and make the min_free_kbytes setting permanent :), or maybe disable the over commit to let Planeshift client fail and possibly crash earlier on out of memory conditions.
