Error in WRF-CHEM while running ./wrf.exe

I was trying to give a trial run in wrf-chem for 3 days using the mozcart chemistry option. After giving the command ./wrf.exe, it starts generating wrfout* hourly output files. It generated 6 hourly output files .But after that it stopped running and gave a segmentation fault error. I have mentioned the error below. I am using WRF V4.6.1 model.

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.
