wrf.exe crashed after sometime with out any error

[sunil_babu]

Hey guys....
I am running wrf 4.1.4 version for the year 2015 by month wise.
the model was successful for all the months except April, May, and December.
everything(input data, parameterizations,...) is the same for all the months except date change.
But don't know why, the model is giving segmentation fault error after running for some time(for Dec month 9hrs, April-26hrs, May-20hrs).
I checked for the memory, there is no issue. After the model getting crashed I ran the model for the month of September, the simulation was completed without any error.
I freshly downloaded gfs input data & SSTdata again and tried but still, the model is getting crashed exactly at the same point as the previous run.

What can it be? Any ideas?

Thanks in advance

Please take a look at your wrfout files right before the model crashed and see whether you can find something unusual, NAN or unreasonable pattern of certain variables.
If all looks normal, you may save wrfrst file a few time steps before the model crashed, then restart and save wrfout at every time step. Hopefully in this way you can find some hints when and where the model went wrong first.
Another option is, you can compile WRF with ./configure -D, then rerun the failed case. This will give you information where the problem first popped up.
