The container runs nginx, mysql, php-fpm with no issues. Hostnode is CentOS 6. Both the hostnode and the container have been restarted since recent updates.

Other containers (Ubuntu 12.04, Debian 7) show normal memory reporting.

Not sure when this started, didn't notice until now...

I have the same problem with a provider. It something at the hosts level. Literally all usage is seen as "cache".

Probably a kernel bug - that kernel is very recent, was released just a few days ago.

Report it here, please - https://bugzilla.openvz.org/

We face similar to OpenVZ. Hopefully the bug will be fixed soon.

Stop spamming and grow up.

Thanks @cociu for bumping this. I'd forgotten....

If anyone has an OpenVz with a recent kernel and are wondering about the accuracy of "free", you can try my "ofree" script....
