Hello Glenn and Roy,
I can't say for certain where these particular files came from, since
they arrived at NCAR well before I did, but I'll be sure to ask around
tomorrow. The timestamp on them is 2007 but I'm fairly confident we
archived them much closer to the datetime in the filename. I do know
that we get our current files from NCEP NOMADS.
http://nomads.ncep.noaa.gov/pub/data/nccf/com/gfs/prod/gdas.YYYYmmdd/gdas1.tHHz.pgrbf00.grib2
I'm pretty certain these older ones originated from NCEP as well.

Agreed Roy.
Grib was a great transmission standard back in 1975! Yes, tables go
stale.
Kevin, I too would like to know the source of these data.
Regards, Glenn

Hi Kevin:
I already ran into this with data from FNMOC, and reported it (is
that where your GRIB files are from?). At one point they thought
they had a fix, but when i tried it things got mucked up.
So this is one they are aware of, and hopefully 4.3.17 will have a
fix. At the same time, in our case, I know they didn't really use
a different table, and this is sloppy on the providers part, and
also is one of the many problems with using external tables.

I do not know if this already being covered or not. I came across
the error in the subject line when I expanded my TDS catalog
config to cover the extent of my dataset. This caused an Error
500 when trying to view Best Timeseries data via any of the TDS
access types/services.

isolated this error to a period spanning two months in 1999 (Aug &
Sep). After converting the GRIB1 files to netCDF and dumping the
netCDF headers, the only variation I see with the Pressure_surface
variable is that some use Grib1_TableVersion = 1 and the rest use
version 2:
