Yup... that's about what I got for my troubles. After turning off all 
the unneeded modules, they are now running about 17mb. Not a huge 

I definitely need more ram and I have it on order. While I'm waiting for 
it, I figured I'd see what processes I could slim down.

My basic problem is at peak usage times (usually in the afternoon), the 
server starts using swap space, and then response times really bog down.

This is on a 'spare' server that is temporarily in service while one of 
our 'big' servers is out for repair. This 'spare' server only has 1G ram 
and was never really meant for web server service.

It's trying it's best. I'm just trying to lighten the load for it.
