Description

Some of the INFO level log4j entries are not really useful, for example in SocketServer.Processor, due to metadata requests that reply on a separate and short-lived socket, the following log can be constantly printed:

info("Closing socket connection to %s.".format(channelFor(key).socket.getInetAddress))

We'd better move them to DEBUG if they are expected in normal state.
