CESM 2.1.3 POP initialization hangs during hybrid run

[zhangguangzhi]

I’m running CESM 2.1.3 with configuration --res f09_g17 --compset B1850.
I didn’t modify the source code, only the usual XML settings listed below.
During initialization, the model stops when the POP component starts to initialize — it just hangs with no further progress.
