wrf.exe loop

[rojain10]

Hello,
I am coming across an error where while running wrf.exe, the first wrfout file for both of my domains are produced, but then the model suddenly stops updating the rsl, wrfout, and pt_ files, but still continues to "run" despite nothing happening. There are no errors being shown in my rsl.error.0000 and rsl.out.0000 files. I have attached my rsl files and namelist.input to this post.
Thanks for your time!

Hi Rohan,
In searching the rsl.error.* files, I found many CFL errors:

rsl.out.0141:d02 2011-08-26_00:01:30         6137  points exceeded cfl=2 in domain d02 at time 2011-08-26_00:01:30 hours

This typically means that the model has become unstable, often due to complex terrain. Take a look at this FAQ that provides potential solutions for CFL errors:
