Daniel, you may be aware of this, but a 3-node Riak cluster is not recommended and may be playing a minor role in your resource problems. Every request will hit every server (except for some requests that are being made twice against a single server, making I/O that much worse), and depending on your request parameters the loss of a single node may result in failed reads and/or writes.
