Description Christian Völker

Memory leaking processes cause a system to use swap space (extremely slowing down the entire system) and finally falls into a out-of-memory situation.

The oom can not guarantee to kill the failing process which could lead into a system without important services.

Similar issue applies to a process hogging CPU.

systemd offers cgroups to limit the resource usage (see URL and https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/system_administrators_guide/sect-Managing_Services_with_systemd-Unit_Files#sect-Managing_Services_with_systemd-Unit_File_Modify)


Currently administrator has to set the desired values in file named "*.conf" in a (to be created manually) directory named "service.d" under  /etc/systemd/system

Would be great to have ucr variables and templates for these files to be created:
systemd/ssh/MemoryAccounting=(y/n)
systemd/ssh/MemoryLimit=1G

So global syntax could be
systemd/<SERVICE>/<VALUE>
