    Handle socket.gethostbyaddr() exceptions when verifying hostnames.
    
    Log any socket exceptions raised and let the process continue. This
    failure isn't a show-stopper. Other checks past this will catch any
    other problems.
    
    This was seen when /etc/hosts and /etc/resolv.conf were both empty.
