Description

In trying to debug some problems with the pluggable authentication, I noticed that we are eating the IOException without logging it (at any level) in ServerRpcConnection.

This makes it super hard to debug when that pluggable interface has a problem because the context gets lost (clients just get a pretty useless DNRIOE).
