As suggested by @Fortuna [in the other thread on the same topic](https://forum.cmascenter.org/t/question-in-runing-cctm/5514/2), you will need to look at the main log file to see what is happening at the end of the `while` loop in the run script when `TODAYG` and `TODAYJ` are being incremented, the script loops to the next day, and a new 24 hour model execution is started. The CTM\_LOG files you posted show that the first day finishes successfully, so it’s something in the looping that’s not working as intended. This would be captured in the main log file, not the CTM\_LOG files.
