Error in vortex-following runs: ESMF_TimeIntervalQuotI: divide by zero

Hi, I am running a 36-hour typhoon simulation that combines static nested domains (d01, d02, d03) with a moving domain (d04, whose parent domain is d01). The model consistently stops with the following fatal error at specific times:
ESMF_TimeIntervalQuotI: divide by zero
This occurs exactly at the hour mark corresponding to the vortex_interval value, and it appears completely unrelated to the time_to_move setting.

Example:
vortex_interval = 11 → crash at 11 h
vortex_interval = 13 → crash at 13 h

If vortex_interval is set to a divisor of 60 (e.g., 10, 12, 15, 20, 30), the model crashes at 1 h. Thus, regardless of the setting, any simulation longer than 12–13 hours eventually fails.
In order to completely run the full 36-hour simulation, I once considered performing a restart before the simulation interruption, but the restart was not successful. I do not know if it is because of 'io_form_restart = 102' (the reason it was not set to 2 is that the restart file exceeds 2GB, which would cause the simulation to interruption). Therefore, I am very confused: how exactly should I resolve this ESMF_TimeIntervalQuotI error? How can I successfully complete the 36-hour simulation?
