Hello, First I hope this mailing list is the proper one for asking the following question: I do the following, as root, on Fedora 20 with 3.12.7-300.fc20.x86_64 kernel: create a cgroup called "0" /sys/fs/cgroup/memory/0 run: echo "1" > /sys/fs/cgroup/memory/0/memory.oom_control bash: echo: write error: Invalid argument Why am I having this error ? According to the documentation: http://lxr.free-electrons.com/source/Documentation/cgroups/memory.txt this should work.
