That is normal. Any extra memory that your processes don't use is used by the OS for things like file caching. If you had memory problems you would see lots of stuff in swap.

[Shadowrunner]

What kernel are you running ?

uname -a

if it's 2.4.18-3 (redhat 7.3 default) then that would be the problem as it has horrid memory management problems (along with many others). Easy fix tho, just build a new one

you should turn of rpc.statd unless you are mounting NFS partitions.

apmd on a server ? i use it on my laptop but not on a server..

what is with plesk AND webmin, does plesk not allow you to control most of that stuff ?
