Subject: oom-killer: - error_code messages?
Hi all,
I just experienced a oom kill, (never seen before). I was running
sa-learn --spam on a 165M folder.
System: 2.6.16.18
free (after the oom).
total used free shared buffers cached
Mem: 257344 24656 232688 0 1180 9400
-/+ buffers/cache: 14076 243268
Swap: 136512 19824 116688
BTW, swap is set at this as the box was once a 64M machine, and I have never
ever seen swap usage > 10M so I never added to it on RAM upgrades over the
years - could this be the issue?
My question is this - should I be seeing the do_page_fault and error_code
messages like this?
Thanks,
Nick
