Hi @giampq, The solution here is to alter the line in: /etc/default/grub. The docker container uses the kernel from the host so the host should have the cgroup support which is needed. After you changed this you should restart so you can have the additional memory features.

If you have additional questions could you ask them on the Slack (https://www.domjudge.org/chat) as this is not really a bug so more people might be able to help you there.
