[gradsusr] Random Problem Running GrADS in Batch Mode

[Tyler Jankoski]

I use GrADS to generate RTMA temperature graphics every hour. Cron runs my scripts and GrADS generates the graphics in batch mode.

About once or twice a day, the graphic output doesn’t work. I get this error message:

Failed to open file.

*** FATAL ERROR: could not open file: rtma2p5.t21z.2dvaranal_ndfd.grb2 ***

Big problem:
  either rtma2p5.t21z.2dvaranal_ndfd.grb2 is missing or not a grib file
  or wgrib2 is not on your path or wgrib2 is too old
  or can not write to /tmp/g.28979.0.tmp (full disk or permissions).
Open Error:  missing XDEF record 
Open Error:  missing YDEF record 
Open Error:  missing ZDEF record 
Open Error:  missing TDEF record 
Open Error:  missing UNDEF record 
Open Error:  missing DSET record 
Open Error:  missing VARS record 
  The data file was not opened.

Any idea what is causing this?
