First of all, thank you very much for your reply.
Sorry, if I reply only now, it took time to do tests.

I suppose, the Grib is read sequentially?
I don't understand, why does mapserver crash?
Ideas?
I will create a more useful grib file cutting the values:
0.026779175 to 0
7.122749175 to 7.1
and I will check the performance.
Thank you!!!
