Hello,A bug was recently fixed in cgmanager that may have caused the issue you are describing. Does upgrading your cgmanager and systemd-shim versions to those in Sid (0.33-2 and 8-3, respectively) solve this issue? If you are unable to upgrade those packages, you can try to add `cgroup_enable=memory` to the kernel command line and see if that fixes the issue.
Thanks for taking the time, -- Cameron Norman
