Problem in judgedeamon script

Hello, I am trying to run on a fresh installed domjudge (maintainer conf) server. After launching the ./bin/judgedeamon I got the following crash when the first submission is made for a contest.

[Aug 03 15:25:02.335] judgedaemon[16141]: Running compile.sh caused a runguard error/crash: 'runguard error - 50029 - creating cgroup'

And after the participants can't submit any more solutions.

Did you already face this problem?

I have seen the issue:* https://github.com/DOMjudge/domjudge-packaging/issues/11 https://github.com/DOMjudge/domjudge-packaging/issues/11*

But I didn't understood how they manage to fix it. Is there a way to reinstall all the cgroup from scratch?
