Sorry, at Unidata we have no experience with the MOM-5 model, and the error
message above comes from the "run_regrid_3d.sh" shell script, rather than
directtly from the netCDF library.  As a guess, it's possible that the 
"_FillValue" attribute for the variable you are trying to regrid is not of
the same type as the variable.  For example, if the variable was of type 
"real", "float", or "double" and the associated "_FillValue" attribute was
specified as a character string, such as 

  salinity:_FillValue = "-999.0" ;

instead of 

  salinity:_FillValue = -999.0 ;

you might get such an error, but that's just a guess ...
