You would really be best off just turning off the oom_killer.. Of
course, you should probably also figure out what process is actually
chewing through your memory to the point that the OOM killer is getting
run.

There's probably something else that's trying to grab all the memory and
then tries to use it and PG ends up getting nailed because the kernel
over-attributes memory to it. You should be looking for that other
process..
