Issue cgroups problems

[Oshikuru]

Hi,

with the help of plesk support I now have the system ressource controller running.
I set up (just for testing purposes) 8MB memory limit (4MB soft).
How can I test now if it works? I tried to consume memory with the user that has set these limits, and I can consume more memory than 8MB.
How do I find out if the values were set correctly by plesk?

For me it looks like there is no limit, since the value "memory.kmem.limit_in_bytes" is 9223372036854771712.

Can you please help me to make cgroups work?
