WRF stops silently after proceeding to few “time for writing output” steps

I am trying to run WRF-LES for 34 hours of simulation. wrf.exe proceeds normally but it silently stop after proceeding to few steps with rsl file saying “time for writing output”
There’s no error in the rsl files.
For the same simulation of 10hours it ran fine.
But then i have changed the microphysics from thompson to morrison double moment.
I am not sure if it is the issue.
I am currently using 64 processors but i have tried with changing the processors count but the problem seems to persist.
 
Would you please clarify your approach?

In WRF-LES, no microphysics option is turned on. WRF-LES is designed for producing a large-eddy simulation (LES) of a free convective boundary layer. All physics options except surface layer physics are turned off.

Are you actually running WRF for real-data case?
 
I m running for real data case, with most of the physics turned on focussing on fog development.
Specifically using thompson, with pbl option turned of for the LES domain.
 
Hi,

I looked at your namelist.input and have a few concerns. Would you please change the options as I list below, then try again?

km_opt = 5, 5, 5

diff_opt = 2, 2, 2

bl_pbl_physics = 0, 0, 0

sf_surface_physics = 2, 2, 2

sfs_opt = 0, 0, 0

time_step = 4

time_step_fract_num = 5,

time_step_fract_den = 10,

hybrid_opt = 2

Please let me know how it works. Thanks.
