gancgrid error: unable to allocate memory for grtmp grid storage

[Jennifer Adams]

That shouldn't be a big memory request: 145*73*1*1*1*8. Does  
'display' work, or do you get the error only with 'define'? If the  
error is reproducible, could you please send the shortest possible  
script to illustrate the error and the output from ncdump -c on your  
netcdf file?
