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 linux-mm@kvack.org to the cc, but you removed it; please
don't do that.
