The interface between the kernel cgroup functionality -- both to monitor 
and control usage is via a (virtual) filesystem.  If this filesystem 
isn't mounted, HTCondor can not use cgroups. Unfortunately, there's no 
standard way to mount the filesystem (or standard place to mount it, for 
that matter) across Linux distributions.  You can mount it "by hand" 
with the mount command, or the cgconfig service on some distros will 
mount it, or systemd will mount it on distros that run that.

On Centos/SL 6 the cgconfig service can mount the cgroups for you. Do 
you have that service running with an appropriate /etc/cgconfig.conf?
