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