The file sizes are around 24mb, which is typical I believe for the format of 
these files.

I was able to display the data in IDV Kevin.
We upgraded to GEMPAK7 and still have GEMPAK6.7 installed as well.

I am thinking it's a decoding issue as I am using these two actions in our ldm 
One for storing grib2 files and one for decoding into gem files.  

CONDUIT prod/nam\.(........)/nam\.t(..)z\.awip12(..)
        FILE    -log /atmo/data/gempak/model/nam12km/grib2/\1\2_fh_\3.grib2

NGRID|CONDUIT   (^[LM].B... KWBE|prod/nam.*awip12)
        PIPE    /opt/gempak/GEMPAK7/os/linux64/bin/dcgrib2 -d 
                -e GEMTBL=/opt/gempak/GEMPAK7/gempak/tables

I will this theory tonight by not filing grib2 data tonight.

Check the file size.  I don't think GEMPAK can read files over 2 GB though it 
may be able to create them.
