When ca_lw_physics turn on the simulation interrupted, turn off (ca_lw_physics=0) the WRF model can run normally?

[Yiwen-Hu]

Dear,
I encountered a problem when running WRF model, when setting ca_lw_physics=0, the model can run normally (3 nested, 15X5X1km), when ca_lw_physics=4 (or other options), the model integration will be interrupted for a period of time, if it is 27X9X3km resolution, the setting ca_lw_physics=4 can run, how to solve this problem? (We use WRF4.0 model to simulation)
Thank you in advance,

Wei，

Wei,
Which version of WRF did you run?
can you upload your namelist.input for me to take a look?
