free-m doesnt match with ps aux count
I got a 2GB memory droplet and seems like my free-m is not couting correct my free memory OR something is using more than it should..
I did some reasearch and i found that i can "count" my usar memory by this command:
ps -e -orss=,args= | sort -b -k1,1n | pr -TW$COLUMNS
Quick math all my main process are using 500MB memory.. with the minor ones.. it should reach 600MB top.
but free -m show that i only have 300MB left... and 800MB cached..
Just to you know i running 4 nodejs applications (3 ghost blogs and 1 express)
Any thoughts about it?
