    Description

      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.
