Reported memory usage doesn't tally with top
I have an Ubuntu server which seems to be using more RAM/swap than the listed processes would suggest.
In htop, these are the stats:
Mem = 653MB of 1006MB
Swap = 474MB of 2498MB
Why is swap being used if there's free RAM?
The greediest process is taking 17% of RAM. How can I total the processes' RAM usage apart from using top/htop?
