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
