Where's the hog?

[ChePazzo]

So, I'm trying to figure out why I'm maxing out my 1GB of RAM. maybe I'm just reading this wrong, but this doesn't look good.

Here's what I'm not getting. 99% Mem util. But nothing seems to be adding up to 1018080kB under the RES column and the %MEM column doesn't seem to add to 99%..

Should I be concerned?

I'm going to say this is pretty average. On my mail box at work, running Centos 4 I've got 1.5g, and average around 26564k free at any given time. Uses a bunch for cache & such.

[_Demo_]

There is nothing to be worried about with this usage. You have around 750 megs being used for cache :

751744k cached

If programs need memory then the cache will go down.

oh good. thank you!

If I never hook up a monitor to the PC, do I even need to run X?
