It sounds like cgroups are not properly enabled. Did you follow the instructions to set up a judgehost: ?

In particular, check that "cat /proc/cmdline" shows "cgroup_enable=memory swapaccount=1" and run the misc-tools/create_cgroups script (this must be done after *each* reboot, so you might want to call it from /etc/rc.local for example).
