Yeah, resize not applicable in your situation. Are you planning on
having 20 or more nodes eventually?

Just so I'm clear, that "htop" output (https://goo.gl/k8Wtcw) is from
one node, correct? There shouldn't be more than one beam.smp process

different PIDs listed, but I've only ever used top or the varios "sar"
