That's absolutely alright as Linux manages memory in a different way than windows. You should read my article "Linux server loads explained" in articles section. Try using free -m and see the explanation in that article.


Hi,

Thanks. - That is an interesting article.

free -m shows:
total used free shared buffers cached
Mem: 998 941 57 0 171 455
-/+ buffers/cache: 314 684
Swap: 1992 0 1992

I am still concerned about the amount showing as used, even though the buffer shows 684 free. The machine has 1GB of ram.

Does this look normal to you ??

Also, here is a copy of the latest 'top' too:

top - 07:41:45 up 1 day, 7:32, 2 users, load average: 0.00, 0.00, 0.00
Tasks: 115 total, 1 running, 114 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.0% us, 0.0% sy, 0.0% ni, 100.0% id, 0.0% wa, 0.0% hi, 0.0% si
Mem: 1022928k total, 964280k used, 58648k free, 175212k buffers
Swap: 2040212k total, 4k used, 2040208k free, 466568k cached

Thanks again,
Daniel

Yes, it looks normal to me. You can see the percentage of memory usage by each application/process using the "ps auxf" command.
