Hello,

I am running the cime workflow on Orion. There is an error message when ./case.setup:

./case.setup

In your case you can adjust this value in env_mach_specific.xml

For all cases adjust it in cime/config/ufs/machines/config_machines.xml in the section for Machine Orion.  If you do this please consider submitting a PR to the cime repository with the required change.

Thank you for your reply. Should I change RLIMIT_STACK from -1 to  300000000 in the env_mach_specific.xml?  The case.setup passed without error messages, But the case.build is hanging now without staring to compile ufs.exe. Thank you again for your time and help!

Yes change RLIMIT_STACK from -1 to  300000000 in the env_mach_specific.xml.

Are you sure it's hanging?  The build process for ufs takes several minutes and doesn't update status.  I would suggest checking back after about 10 minutes before you assume that it's hanging.
