All,
We have noticed a strange problem with the grids coming in for the 0.5
degree GFS files. The problem started with the 12 UTC run of the
2015/04/22 run, and several files (though not always the same ones) have
been missing grids in each run since. The complete files contain 366
grids, the incomplete files always contain 327 and are always missing
exactly the following grids:

I don't think it's a latency issue for us, because our latencies for
conduit have been < 30 seconds or so for at least the past 3 days.
One curious thing, the files are complete on motherlode.ucar.edu, but
the files that we have as short, have a later modification time than the
rest. For example, for the 12 UTC 23 run, we were missing grids for the
F021, F102, F123 and F252 times. Here's a subset of the times on
motherlode that shows these files:

We are feeding redundantly from conduit.ncep.noaa.gov and
ncepldm4.woc.noaa.gov
Ideas?
Here is a (I think) complete list of the times that had short files
since 12UTC 4/22. I'm guessing all of these files are complete on
motherlode, but have a later modification time than the rest of the run.
