I think this might be a dupe. CCing Xan who should definitely know.

The trace is different, but it definitely looks like bug 42756. To double check enable overcommit and see if it stops happening (echo 1 > /proc/sys/vm/overcommit).

Comment 3 jens.timmerman 2011-02-03 12:23:57 PST

echo 1 > /proc/sys/vm/overcommit_memory
does fix the problem!
