Description of problem: The kernel is not configured CONFIG_CGROUP_MEM_RES_CTLR thus making memory resource controller usage impossible. Please enable CONFIG_CGROUP_MEM_RES_CTLR. Version-Release number of selected component (if applicable): kernel-2.6.27-0.398.rc9.fc10.i686
I don't think we can enable the memory resource controller this close to release. All of the testing so far has been without it enabled.
Thanks for the additional info. This is might wrong place to start this discussion but closely related to this is missing support for RSS ulimit enforcement. Currently, setting RSS ulimit has no effect at all and I doubt just by enabling CONFIG_CGROUP_MEM_RES_CTLR would make it work. FWIW, some patches for that have been floating around in the past: http://lwn.net/Articles/96859/
CONFIG_CGROUP_MEM_RES_CTLR is now enabled in F11 rawhide.
