Hi list,
I'm running Fedora Core 1 with 512 MB RAM and 1 Ghz CPU.
I noticed that even without any apps running, the machine seems to be using
a lot of RAM and I can't figure out what and why.
Here's the top output

I suppose cached/buffered memory are "free" because free gives the following
output
total used free shared buffers cached
Mem: 501 344 157 0 103 110
-/+ buffers/cache: 130 371
Swap: 1019 0 1019
but still, what's using 130 MB of RAM ?
Thanks,
Yang
