Limit server resources (cgroups)
« 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:

-------------------------

for vps servers you need to disabled disk io limits
VPS & Dedicated server provider with included FREE Managed support for CWP.

*** Don't allow that your server or website is down, choose hosting provider with included expert managed support for your CWP.

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

Thanks for your reply.

Still not working properly... For example, CPU limit is not working.
