> In supporting customers we often see things like SocketTimeoutExceptions or EOFExceptions
coming from DataXceiver, but the logging isn't very good. For example, if we get an IOE while
setting up a connection to the downstream mirror in writeBlock, the IP of the downstream mirror
isn't logged on the DN side.
