WRF-Chem hangs after a few minutes of running

Hi everyone,

I am using WRF-Chem version 4.2.1 and have been able to run it successfully so far with chem opt = 201.
I now modified anthro emissions (e.g adding a diurnal profile and prescribing a vertical distribution to the anthro emissions).
After using these new wrfchemi emissions the model just hangs without any errors and generates a fort.67 file.
I attach here my namelist.input and rsl.error file.

I'd appreciate any help debugging this.

Hi Prerita,

If the only changes you made were to the emissions, please double check that your emission modifications were successful and did not produce spurious values that could crash the chemistry. Also, please look at the tail of other rsl.* files as there are often unique messages in the core that threw the error.
