Abstract:

Nasty OOM killings appear during massive parallel kernel builds with
SLUB, but not with SLAB. By nasty I mean, cc1 processes are killed --
object files in .ccache and tree are corrupted which makes me to
blow up them entirely.


Setup:

92G ext2 partition mounted with noatime. .ccache, master tree, object
trees, build logs residing on it. 2G of RAM, 1G of swap partition.
CFQ scheduler. Core 2 Duo E6400. x86_64 arch.


Workload:

build ~250 configs some fat, some not, in parallel from one source
using O= and save logs to separate dir. This is what I do regularly here.


Observations:

With SLAB this workload never went to OOM killer.
With SLUB and pretty much all debugging enabled, it finishes to the end
(albeit slowly).
With SLUB and no debugging, OOM killer kicks in.

After I notice it at evening, e.g ssh to box doesn't work -- new OOM killings
appear.


Below is dmesg from fresh boot,  OOM messages and .config. Please, give me a
clue on how to proceed from there. If needed I can prepare cut-down scripts
for reproducing and more precise description of setup.
