segmentation fault when running atmosphere_model

Hi,
I encountered a problem with MPAS atmosphere software. I wanted to change the GFS source by using ifs data. The init_atmosphere code runs well but when I launch atmosphere_model it fails with segmentation fault and no error printed. The only thing that is different from usual in the init_atmosphere_model run are these messages:
"
Setting SST from SKINTEMP
Bad sm_fg 0.00000 4 755
Bad sm_fg 0.00000 4 777
Done with soil consistency check
"
which are not pointed as error. What do they mean and could it be the origin of the problem?
Thanks for any tips or insights.

Best
 
The message below indicates that soil moisture is wrong in your input data.

Code:
Bad sm_fg 0.00000 4 755
Bad sm_fg 0.00000 4 777

Specifically, sm_fg(4, 755) and sm_fg(7,777) are 0.0. However, the MPAS initialization program will correct such errors by specifying sm_fg = 0.001. This is why your init_atmosphere can run to the end successfully.

I am suspicious that your input data contains some other errors, which lead to the failure of model run. If this is the case, then the model should crash immediately after it is launched. Let me know if I am wrong.

Please clarify
(1) Is your case a global or regional MPAS run?
(2) How did you get IFS data? Is it a global dataset?
(3) Can you upload two single intermediate files from IFS for me to take a look?

Thanks.
