Title: Limit server resources (cgroups)
Post by: AlexG on March 01, 2019, 09:02:18 PM: Hi everyone, I wonder if someone have issues with Limit server resources (cgroups) (CWP-PRO). I've setup a new policy and I tried to restart the service, there are the logs:

Yes you are right. Support team told me that on VPS KVM, this limits must be disabled.

Thanks for your reply.

Post by: tinchocba on July 09, 2019, 02:33:59 PM: Still not working properly... For example, CPU limit is not working.

Post by: vanthoi on June 29, 2020, 10:22:50 PM: I came across your diary.
It looks like the Disk I/O section of your server is not working.
Common errors on virtual servers such as vmware or kvm.
You want to use the drive speed limiter.
You must fix Disk I/O errors on your system.

Where you still want to use cgroups.
In the installation of Cgroup, put a checkmark in the disk I/O section
Save and restart the service will work.
