Hi Steve.
Pls find attached code for stress application. The test code is very
simple. Just alloc memory.
we got this issue on embedded Target.
After analysis we found that most of task(stress_application) is in D
for uninterruptible sleep.
application state
stress x
stress D
stress x
stress D
stress x
stress D
stress x
sleep D
Thanks

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.

I'm really not familiar with OOM, so I don't know the answer.

I think rather than just adding a mailing list to a message containing
almost no useful content, you may do better to start a new thread
including the linux-mm mailing list, describing the problem that you're
seeing, the kernel messages plus the test program all in a single
message.
I don't think the problem you're reporting is ARM specific - to me it
looks like something is holding on to processes pages after they've
been killed, and only giving them back after the OOM killer has killed
off the last killable task. That's certainly what the "xxx free pages"
values hint at.
