The log messages indicate that the ECMWF LDM can't connect to the
CMA LDM using port 8080.  Because the CMA LDM is running the
"balance" program to connect port 8080 to port 388, it is likely
that the CMA LDM host or the network in and around CMA doesn't
allow incoming connections to port 8080.

I recommend that CMA work to allow incoming connections to port
8080 on its LDM host.

Mike Schmidt's experiments showed a large increase in throughput when
the CMA LDM connected to the NCAR LDM using port 8080 instead of port
388.  It is likely (but not necessary) that this condition also 
exists in the opposite direction.
