Hi Olivier,

Thanks for the links. I see now that there is an option to assign permissions to access control groups for non-root users. I'll try to configure it and post back the results.

Best regards,
Anton

Hi Olivier,

Thanks for the suggestion, but Cgroups is installed and started. As I mentioned, everything works for the root user. Should I do some special configuration for a non-root user? Currently, my /etc/cgconfig.conf contains the following:

mount {
cpuacct = /mnt/cgroups/cpuacct;
}

Thanks,
Anton

You need to install/configure Cgroups on your system :
