The OOM killer is a very dumb (near useless) heuristic. You can turn it
off or switch to sane overcommit module by setting
/proc/sys/vm/overcommit_memory to
1 or 2 respectively.
In this case your bug looks like the 2.6.9 network problem in which case
if you are lucky -ac12 will have fixed it as I merged the stuff DaveM
recommended into that.
