Yup, I was thinking about that one, definitely sounds like a good idea, there 
isn't even a monitor attached normally so there's no screen that we're 
saving.

It has 512MB of RAM rarely using more than 100MB (other than for fs caching), 
I cannot rule out an unusual event that caused a spike in usage though ... 
we're now monitoring that so hopefully it's not so rapid that we don't catch 
it.  The kernel probably does have known issues but it's Debian's latest 
2.4.18-686 so it should be ok from a security point of view at least.
