Hi

I've noticed that my machine becomes unstable from time to time. Currently it's running CentOS 5.1 x64 + Xen 3.1 and 1 domU. The dom0 runs Apache, PHP & MySQL for cacti / graphing, and the domU is a cPanel VPS.

I can't see where / how dom0's memory limit is set, yet I often see it only having 5MB RAM left.

This is just after a restart

After running for a while the memory on dom0 is very little, and it's a bit slow. How do I increase the max mem for dom0 ?
