Hi,

Is there any way to fix this stuff? I'm getting this error on my VPS - /etc/motd_dyn: fork: Cannot allocate memory

Please help me.

Regards,
George

Probably resource shortage.

What about output of
cat /proc/user_beancounters or
cat /proc/bc/[ctid]/resources
or vzubc [ctid] command? Focus on column fail counts.

Simmilar issue here

// last column shows failures count of row parameter (privvmpages), as you can see, there is large number indicating insufficient memory. Everytime, when this resource is not enough, it increments failure counter. Your container is really insufficient with privvmpages.
Post your CT config file, what OpenVZ kernel are you using?

I'm hosting in Hosting24, they do not allow using of CT file, and this is what I received as an answer about the kernel version: OpenVZ operating system-level virtualization technology.

Is there any way to fix this stuff?

Your container encounters memory insufficiency.
Consult it with your VPS provider, when you have not access to hardware node.
