Memory containment

Contain memory by web processes

[ctasma]

We converted several CentOS servers to CloudLinux, and have noticed that people can take down the server with memory usage. I guess I had assumed that memory was contained along with CPU as I was used to with our cgroup setup.

Looking at the documentation, it looks like there is a setting for memory in a future version. Is there a way to get this functionality now on a converted server?

1. Here is info on memory limits: http://www.cloudlinux.com/blog/clnews/46.php
(we might delay public release for another week or so, still debating)
2. Try running:
yum install memmonitor
It install tiny daemon that monitors server memory usage, and kills processes when needed. It still can force server to swap though.
