A cgroup enters the dying state after being deleted.
It remains in that state for an undefined period
(which will depend on system load)
before being destroyed.
while resources are freed before the cgroup is destroyed.
Note that the presence of some cgroups in the dying state is normal,
and is not indicative of any problem.

A process can't be made a member of a dying cgroup,
and a dying cgroup can't be brought back to life.
