Hi Steve, I too have noticed this strange behaviour on my Linux ARM board. I also have 2.6.35.12 installed and I see a similar crash when parallel OOMs are triggerred. I am executing multiple instances of a similar test application which allocates a lot of anonymous memory. OOM then starts kicking in parallel and this eventualy results in a hang situation. Can anyone tell me what patch to apply to solve this problem ? Thanks, Kautuk.
