Hi Christian, Could you check the mm/oom_kill.c for your kernel 2.6.11-rc3?
During the 2.6.11-rc development, the oom killer was changed by Andrea Arcangeli. I do not remember exactly which was the version that this modification was included, perhaps in kernel 2.6.11-rc4. Now this oom killer modification is part of 2.6.11 vanilla kernel. Send the mm/oom_kill.c of 2.6.11-rc3 to me, please. Let me confirm my doubt. BR, Mauricio Lin.
