See the latest build of main branch here: https://buildkite.com/clima/climaatmos-ci/builds/19580#01907559-2d36-4711-856d-c68813e7b7e9. It fails immediately but works when rerunning. We saw something similar in the coupler that 1M jobs may be nondeterministic. @trontrytel Any idea if there could be something not initialized correctly for 1M?

No idea right now. But I'll look into that when I start working on making 1M scheme more stable in Atmos

Sounds good, thanks! It could be radiation too, or some combination of radiation and microphysics, so let me know if you can't find anything, and I'll look into radiation.

Actually I think it might be aerosols (although it doesn't explain the coupler case, which doesn't have aerosols)! I'll add a fix.

Nevermind the aerosol fix didn't fix this. When it breaks both e_int and q_tot are NaNs so maybe it's not radiation, as radiation shouldn't affect q_tot.

I found one more thing. Let's see if #3178 helps. I am still not sure if it's from radiation though.

I don't see it anymore. I will close it for now and we can reopen if if we see it again.
