You only send us two rsl files. And there is no helpful information in these two files except that they tell:
forrtl: severe (174): SIGSEGV, segmentation fault occurred
Note that error messages may appear in any rsl files and don't necessarily be in rsl.out.0000 and rsl.error.0000.
Please check all your rsl files, find errors such as CFL, NaN, etc. You may also look at your wrfout files saved right before the model crash, and see whether the physics variables are reasonable.
