When run on the debug mode, an error in the first hour of the first day of simulation occurs in the standard output:

This is an error I mentioned in another post at ['Could not write CTM\_DEPV\_DIAG file' error](https://forum.cmascenter.org/t/could-not-write-ctm-depv-diag-file-error/1948/6)

I could not reach the aqchem.F iterations related error at HH:MM:SS=20:45:00 in the debug mode because another error was caught at 00:00:00 of the day 2014192.
