Troubles with the Arakawa-Schubert cu_physics

Hello

I'm having an issue that when I try to run the wrf with the Arakawa-Schubert. After starting the wrf, receive following error

Is there a variable that I need to add to my namelist when using Arakawa-Schubert? Or it just my computer set-up? I have assigned 6 nodes and 8 processor to run the wrf.

A quick seg fault may indicate a memory issue. Try adding more nodes.

If you are using Intel 17.0.4, try building with -O2 instead of the default -O3. For some schemes, Intel generates bad code. I've not seen this with Intel 18.0.0. Intel 16 line doesn't have the problem either.
