Error in Obs nudging with WRF - Segmentation fault

[mmkader]

Dear All,
I am trying to insert observation into WRF model. I built the OBS_DOMAIN file as mentioned in the WRF user guide. and edited the required namelist section as well. when I run the model, the model runs for awhile and exit with segemntation fault. as shown
Some specifications
WRF mode. ARW V3.0.1.1
compiler ifort 10.1 dm wih icc and mpich 1.2.6
domain size 19x19x35
these are the last log before the model exits

I checked everything even I get the supported OBS_DOMAIN from the WRF user site and edit for my information and I gets the same error.
Can anyone helps me to find the error.

Is the OBS_nudging also set for the 3rd domain?
It looks like it ran for the 3rd domain, then stopped

Good luck

Yes, it runs for domain three also
