The underlying TCP connection attempt is failing for some reason (not a
reason that is getting logged, unfortunately).  I'd try debugging things
at that level first - make sure you can reach the master address/port with
another program (eg, telnet) and/or do a traffic dump (ethereal, tcpdump)
on the machine when the slave makes its connection attempt.  You might
find the connection is being blocked or failing for some simple reason.
