segmentation fault

I got error while running real.exe.
my period is for one year. when I change to shorter time period like one month I don't get error and real.exe run successfully but for one year period it gives error.
I got WPS output in two case.
I mean I divide one year to two section because of limited period of simulation.
can it be reason?
I tried to run as parallel with one core but in both case (serial and parallel) it gives error.
could some one help me with this error?

Kindly Suggest the ways to overcome the Segmentation fault
A segmentation fault can occur due to many different things. Please post your inquiry as a separate thread and provide some more information on your simulation, including the namelist and out/error files.

I'm not sure I understand what you mean about running one year in 2 sections. Do you mean that you process the met_em files for half the year, and then the other half, but then run real.exe for the full year, using all of the met_em* files? As long as there are no gaps in the data, and you're using the same type of data files, I don't believe this should be an issue. It looks like real.exe stops after 3 months, so it's not even getting to the 6-month mid-point.

Can you check whether you could potentially be running out of disk space to write the large wrfinput_d01 and wrfbdy_d01 files?
