The problem was that UFL's network connection was poor.  You can see this at

    
http://www.unidata.ucar.edu/cgi-bin/rtstats/iddstats_nc?EXP+sasquatch.tamu.edu

Note the spike near 2006-06-07 23:00 UTC.  Any data-products that arrives with
a latency that's greater than the maximum acceptable latency (default 3600
seconds) is ignored.  Note from the above that data-product

    WANAFe02-UFL_20050826T0000_20050826T0000_20050831T0000_84gsr1_Z.nc.gz

was sent around 2006-06-07 22:10 UTC but was received by Sasquatch around
2006-06-07 18:08 CDT (which is about 3480 seconds later).  It seems likely,
therefore, that the two missing products arrived with latencies greater than
3600 seconds.

The "-m" option of ldmadmin(1) can be used to set the maximum acceptable 
latency.
