Memory controller cannot be passed down to a threaded subtree (i.e. you only get memcg for the whole `docker` subtree) because memory controller is not threaded (e.g. two threads that share memory space but could be in two different cgroups make no sense for such a controller). > Any clue?

I suspect because of some threaded controllers were passed down [1] the tree while there are also some internal node processes (see cgroups(7) paragraph beginning with: "The second way of creating a threaded subtree"). To get out of this, your docker(?) needs to migrate all processes down from `docker` cgroup before enabling the memory controller. HTH, Michal [1] `cat /sys/fs/cgroup/docker/cgroup.subtree_control` should tell you
