Riak consumes too much memory

How many nodes are you running? You should aim for around 8-16 vnodes per server (must be a power of 2). So if you're running 5 nodes, you should be fine with 4GB since it'll be approx 12 vnodes per. If you're only running on 1 server, you'll be running 64 vnodes on that single server (which is too many), in which case 4GB is RAM is not near enough.
