Upstream description:

Continuing the investigation that started in https://github.com/cri-o/cri-o/pull/6973

Apparently, sometimes systemd removes the cgroup before conmon can read its memory.events. I don't have any ideas about how to work around that race (in conmon; that is).

Another small issue I found is sometimes OOM can be misdetected because the code use the same static counter variable for both oom and oom_kill, which appears to be wrong.
