Do your log files show your LDM switching feeds when data starts flowing
I can't seem to fully resolve it, but the newer LDM seems to get confused
when you have multiple hosts feeding you the same data types without
specifying PRIMARY ALTERNATE. I dunno, I'm running into all sorts of
strange LDM things lately :(

If I use the following feed pattern [upstream = idd@wisc and bigbird@tamu]:
the data seems to flow down to me in "chunks". What I mean by this is that
is when I run 'ldmadmin watch' I see no data for between 4 and 10 minutes.
Then all of a sudden the last 4-10 minutes worth of data comes down within
a 3 second period. It then holds again...and 4-10 minutes later another
payload of data comes down...etc...etc.
If the *ONLY* thing I change is the feed pattern to:
request WMO ".*" upstream.server.edu
The data feed runs normal.
I'm confused! I, and the upstream, have bandwidth to burn so I'm leaving
the feed as ".*"...my pattern was attempting to conserve bandwidth for the
upstream providers but it seems I did more harm than good.
I havent totally verified this issue but it seems to be the culprit. Can
