What I'm looking for is actually the line below "webserver group" that says:
* use Linux cgroups...: yes/no
But when I logged in to your machine, /root/domjudge-5.1.1/config.log shows that cgroups are disabled. You have the package installed, but have not edited /etc/default/grub, so the kernel doesn't support cgroups yet.
As a side note, you should not install DOMjudge as root user. Instead create a separate user to install it as: DOMjudge will use 'sudo' to obtain root privileges only when needed.
