Eu tenho um servidor IBM com 16 GB de RAM instalado. Inicialmente mostrou 16 GB com
free | grep Mem | awk '{print $2}'
mas agora só mostra
8116136
mas deve mostrar
16439208
Quando faço
dmidecode -t 17 | grep Size
Size: 8192 MB
Size: No Module Installed
Size: No Module Installed
Size: No Module Installed

então, qual pode ser o problema. É um servidor físico.
também com
dmidecode -t 17 | awk '( /Size/ && $2 ~ /^[0-9]+$/ ) { x+=$2 } END{ print "\t" "Installed Ram: " x "MB"}'
este comando eu recebo seguindo:
Installed Ram: 16384MB
Estou realmente preso a isso, vocês podem me ajudar.
O comando top também mostra o seguinte:
top - 13:05:13 up 22:52, 1 user, load average: 0.23, 0.30, 0.27

EDITAR
free -m me dá o seguinte
total used free shared buffers cached
Mem: 7925 1372 6553 0 164 454
-/+ buffers/cache: 753 7172
Swap: 8031 0 8031
uname -a me segue depois
