    The only similar message in the kernel is "Out of memory and no killable
    processes..." and that panics the machine when there are no eligible
    tasks to kill.

    If you're using cpusets or mempolicies, you must ensure that all tasks
    attached to either of them are not set to OOM_DISABLE. It seems unlikely
    that you're using those, so it seems like a system-wide oom condition. Do
    cat /proc/*/oom_score and make sure at least some threads have a non-zero
    badness score. Otherwise, you'll need to adjust their
    /proc/pid/oom_score_adj settings to not be -1000.

    Randy also added to the cc, but you removed it; please
    don't do that.
