Donna,

Why are you requesting the same data twice from the same upstream host? I
wouldn't.

That's correct and as it should be. The rtstats(1) process on Curoi will 
consider ldm-relay0.tamu.edu and 165.91.55.26 to be separate hosts and report
them separately.

What duplicates?

The LDM should receive the same data-products regardless of whether or not
the REQUEST entry with the IP address exists or not. The only difference
should be in the rtstats(1) reporting: the data-products will be reported
as being received from one upstream LDM or split between two upstream LDM-s.
