page allocation failure. order:3, mode:0x20
Just noticed nasty looking errors in my log files, which I'll include a small
sample of below.
I'm guessing this is almost certainly related to my encrypted swap (aes-loop),
but "free" gives:
total used free shared buffers cached
Mem: 385776 360192 25584 0 9192 117384
-/+ buffers/cache: 233616 152160
Swap: 820396 152556 667840
which seems to suggest that swap is working fine at least part of the time.
Anyone seen this before (or know it, for whatever reason)? If not, any ideas?
Maybe I'm completely off-track with blaming encrypted swap for this?
Thanks.
