Hi,

I have a problem when I try to run multi-core judgedaemon.

I followed your document. I setup cgroups, edit etc/cgroup-domjudge.conf:

-- Change cpuset.cpus = 0 => cpuset.= 0-22;

I also add file misctools/create_cgroups to /etc/cgconf.d/cgroup-domjudge.

After that, I check /cgroup/cpuset/domjudge/cpuset.cpus => Output is 0-23.

I also build runguard after I config cgroups.

But I only can run 8 judgedaemon. From judge 9th, if it compile any code, I will receive this error:

Compiling failed with exitcode 255, compiler output:
/domjudge/judgehost/bin/runguard: illegal user specified: 7809
Try `/domjudge/judgehost/bin/runguard --help' for more information.

I set all user is user that I run domjudge. But judge 8 judge can compile well.

Please help me! Thank you!
