GEMPAK Support,

I have been encountering some issues with getting GARP 2.1 to load surface 
observations.  GARP has a tendency to crash and work intermittently while it 
adds and loads the file list.

The surface observation gem files end in *_sao.gem, but I believe our LDM feed 
also adds *_shb.gem (ship and buoy observations) to the same directory.  Even 
when I move the *_shb.gem files out of this same directory, GARP may still 
crash.

When I use the different verbose levels and view some of the output, I receive 
some of the following messages during my multiple attempts to get the surface 
observations to display:
--

GEMPAK: [SF -6]  File is not a surface data file.

Is there a way to resolve any of the issues to get GARP to not crash when 
attempting to open these surface observations?  Is there something that I need 
to reconfigure or update with GEMPAK or GARP to get it working appropriately?

Please advise and let me know if you need any additional information.  Thank 
you very much for your time and help.
