* Out of memory condition [not found] <CALJXSJrtf7wid5xS4H5+E6ws_SjcgjB48ppoU_9+24JSkggKUw@mail.gmail.com> @ 2012-10-03 14:25 ` Jérôme Poulin 2012-10-03 20:52 ` Josef Bacik 0 siblings, 1 reply; 7+ messages in thread From: Jérôme Poulin @ 2012-10-03 14:25 UTC (permalink / raw) To: linux-btrfs I don't know how to diagnose the problem, but now it is the second time. After starting a VM in VirtualBox and filling the memory, Chrome stopped loading any pages. After logging out and on, it still wasn't working, reboot fixed it. This time, I've had the same problem and took the backtrace. Chrome starts but doesn't load any pages, I guess it is stuck reading a file as many chrome process are in state 'Ds' but are still killable, Chrome seems really hard to strace bu anyway strace freezes in D state too when attached to a running process. The whole filesystem is BTRFS.
