Hi there
I'm running Ubuntu 8.04 on the VPS (image provided by Bitfolk) and periodically the
VPS seems to lock up and I get the following scrolling really fast on the console:

[1366238.352077] =======================
I've increased the swapfile size to 1GB as I noticed we were using it pretty heavily.
The VPS runs a couple of websites, backed by MySQL.
Any ideas?
