Why so much used? ps aux displays a few httpds and mysqlds as the
highest by far, but adding up to only a small percentage ( < 25% for all
httpds and mysqlds, and minute amounts for everything else).

It doesn't seem to make my system run slowly, but it concerns me definately.


Linux keeps disk blocks in memory for faster access, in your server
there are 158Mb aprox. in buffers. This amount will grow/shrink
dinamically depending on the number of processes you're running. When
the memory becomes full linux will start to use swap. In your server
there is no much swap used, so all seems to be fine to me.


HTH

Thanks to both of the people who have responded so far. I am glad to know it is working fine. I never noticed that much use of ram on any of my other systems ( I probably never checked ), so it had me worried :)
