Dear WRF users, WRF Help,

Recently I've experienced a few crashes of WPP (V3.1).  Once during
the processing of the geopotential field (height of level) near the
surface (1000 mbar), this time it's the temperature field.  The
program crashes in the grib encoding routines.

forrtl: severe (174): SIGSEGV, segmentation fault occurred

I've seen this happen twice now, it's reproducible once it occurs.
I've tried debugging in the MDL2P routine, but I don't see anything
unreasonable in there.

Has anyone seen this happen before, any ideas what might be wrong /
how to fix it?

Kind regards,
     Hein Zelle
