Disable Control Group Rules Engine (cgred) The 'cgred' service moves tasks into control groups according to parameters set in the '/etc/cgrules.conf' configuration file. The 'cgred' service can be disabled with the following command: '$ sudo systemctl disable cgred'

Unless control groups are used to manage system resources, running the cgred service service is not necessary. Fix: # # Disable cgred.service for all systemd targets # systemctl disable cgred.service # # Stop cgred.service if currently running # systemctl stop cgred.service
