Hello,

Sorry for the lack of input about this issue. I currently only have remote
access to the machine for which i had this problem, and i'm not confident
with rebooting into potentially broken kernels. That's why i haven't done any
more tests yet..
I will try to reproduce the issue on another machine first, and if i that does
not work i will find a way to test as you suggest.

Also, I have seen in the lkml archives that someone else seems to have the
same problem:
OOM-Killer kills too much with 2.6.32.2
From: Roman Jarosz
Date: Thu Jan 14 2010 - 08:13:36 EST

As i can't have his email from the web archives, could you plase CC: him on
this thread? Maybe he could also help with some tests.

Regards,

Arnaud
