I have 8GB RAM on my CentOS box that runs apache and samba serving 1 other host on my network. That is to say it should NOT be using 6GB of RAM.
Code:
[root ~]# free -m
total used free shared buffers cached
Mem: 7529 7216 312 0 220 1661
-/+ buffers/cache: 5335 2194
Swap: 7663 0 7663

[root ~]# ps h -eo vsz | sort -n | awk '{s+=$1}END{print s}'
3877852
Summary
free -m shows 2194MB free
ps shows ~4GB used (I realize this may not be a good metric since its VM)
How do I find where all this memory is going? The only services this box is running that are not default: apache and samba. No users on this box. Run level 3 (no gui).
