Yes, mine is ubuntu system provided by a VPS service of
https://crissic.net/los-angeles_vps_pre-launch
I think it's a possibility. I may need to ask the provider about it..
Although I do not think this information will be helpful, this is my kernel
version.
root at okapi:~# uname -a
Linux okapi 2.6.32-042stab093.5 #1 SMP Wed Sep 10 17:39:49 MSK 2014 x86_64
x86_64 x86_64 GNU/Linux
I think I've never changed the kernel by myself.

I had removed cgroup-bin.
But unfortunately it looks like it was not fixed.

Each file after removing cgroup-bin, reboot and re-login is now as follows:

root at okapi:~# cat /proc/self/cgroup

3:freezer,devices,name=container:/12042
2:cpuacct,cpu,cpuset,name=fairsched:/12042
