Yes, i'm really using freezer cgroup BUT i was checking if it's not doing problems - unfortunately, several days passed from that day and now i don't fully remember if i was checking it for both cases (unremoveabled cgroups and these freezed processes holding web server port). I'm 100% sure i was checking it for unremoveable cgroups but not so sure for the other problem (i had to act quickly in that case). Are you sure (from stacks) that freezer cgroup was enabled there?

Btw, what about that other stacks? I mean this file:
http://watchdog.sk/lkml/memcg-bug-7.tar.gz

It was taken while running the kernel with your patch and from cgroup which was under unresolveable OOM (just like my very original problem).

Thank you!
