I created a child cgroup under parent cgroup and running processes periodically under child. However after sometime, I see that the child cgroup automatically gets deleted. What could be the reason ? Any config while creating child cgroup that tells not to delete the cgroup, even if there are no processes attached to it for quite a long time ?

I remember that it comes as "/sbin/rmmod" by default, I think the code I gave below will not delete any group you will create from now on.

echo "" > /sys/fs/cgroup/release_agent

I hope it works

  • @mbravo - Is child cgroup deleted ? what is the duration after which the child cgroup gets deleted if there is no process running under it ? – user3082802 Mar 16 '23 at 09:56
  • I couldn't remember, but I did some research, it was deleted after the last process on it. – mrbravo Mar 16 '23 at 10:23
