AFAICS, if a cgroup cannot be shrunk back to its low limit (e.g. because it consumes anon memory, and there's no swap), it will get on with it. Is it considered to be a problem? Are there any plans to fix it, e.g. by invoking OOM-killer in a cgroup that is above its low limit if we fail to reclaim from it?
Thanks, Vladimir
