I think I'm having the same issue.
I've 2 systems with 4GB of RAM and 2GB of swap that kill processes when
they get a lot of disk I/O. I've attached the full dmesg output which
includes portions where it killed stuff despite having massive amounts of
free memory.

I'm running a 2.6.11 kernel. I have 1 gig of RAM and 1 gig of swap. Lately
when my RAM gets full, the oom-killer takes out either Mozilla or
Thunderbird (my two biggest memory hogs), even though my swap space is only
20% full. I still have ~800 MB of free swap space, so shouldn't the kernel
push Moz or T-bird into swap instead of oom-killing it? At their maximum
memory-hogging capacity, neither Moz nor T-bird is ever using more than 200 MB.
You cut out the important part where it printed out memory usage
information at the time of the OOM, please post it

Yeah this indeed looks strange. gfp_mask == GFP_HIGHUSER | __GFP_ZERO
iirc Andrea fixing up some all_unreclaimable bug in 2.6.11 but this
looks like that for some reason it didn't go into the Normal zone which
has plenty of free pages...
Anthony, are you certain that this was the only VM dump available?
AFAICS the only possible explanation for a OOM kill manifestation under
this conditions (free pages count in the normal zone is higher than
its high watermark + lowmem reservation), is a higher order allocation.
Why the heck doesnt the OOM killer print the order of current allocation?
Anyway, the current try_to_free_pages/alloc_pages interaction seem to
continue susceptible to deliberate decisions, even after Nick changed
the algorithm to return success if the total count of reclaimed pages
is greater than SWAP_CLUSTER_MAX, instead of a single priority pass
being greater than SWAP_CLUSTER_MAX.
It sounds to me that a more reliable indication of OOM is failure to
free _any_ pages after a full priority decay.
Nick, Andrew?
