[Wrf-users] Help with WRF outputting problem

Dear WRF-Users and Wrfhelp:

I am running WRF3.7.1 with sst_update and tmn_update turned on for a year-long integration. The WRF completed successfully, but I am confused on why I am getting wrfout at all time points (6-hourly output) the same as initial time. I didn't check all of the variables, but T2 and TSLB are all the same as shown by ncview as well as ncl. I had a full-year of integration and another two-day test, both have the same problem. I would appreciate if anyone could help pinpointing what has caused the problem.

Thanks for your time, and below is the namelist.input file:
