[Users] help to optimize container

Hi Roberto,

My experience is that you could best allocate more memory to your container
and raise the privvmpages to a value higher than the maxheld value. See if
your memory problem is gone or work from there to allocate more resources.

I hope it helped

Cheers,

Esmé

Hello

I have an openvz node with only one container (Cpanel server).

Yesterday I had many memories issues:

"Unable to fork: Cannot allocate memory"

Can someone help me to optimize my node setting ?

I have a 4Gb node and I can use all node resources for the container.

This is my resources output:

http://pastebin.com/iPXnf0Se

It appears this parameter failed:

cat /proc/user_beancounters 
Version: 2.5
       uid  resource                     held              maxheld
barrier                limit              failcnt
            privvmpages                230416              1045032
900000              1000000               363565

This is my node settting:

 cat /etc/vz/conf/100.conf
