红帽全球峰会25.15. Removing transient control groups
You can use the systemd system and service manager to remove transient control groups (cgroups) if you no longer need to limit, prioritize, or control access to hardware resources for groups of processes.
Transient cgroups are automatically released when all the processes that a service or a scope unit contains finish.
Procedure
To stop the service unit with all its processes, enter:
# systemctl stop <name>.serviceTo terminate one or more of the unit processes, enter:
# systemctl kill <name>.service --kill-who=PID,… --signal=<signal>The command uses the
--kill-whooption to select process(es) from the control group you want to terminate. To kill multiple processes at the same time, pass a comma-separated list of PIDs. The--signaloption determines the type of POSIX signal to be sent to the specified processes. The default signal is SIGTERM.
