I tried to run WRF with your namelist here. I got what is wrong with it. Change:
input_from_file = .true.,.false.,.false.,
input_from_file = .true.,. .true.,. .true.,.
Then nest input file contains land information will be available. So it should work right way. Please let me know if you have any results.

Thank you very much for looking into this.
Before your suggestion, I also tried to run WRF 3.2. Running without
nudging went through but running with nudging stopped for the same
reason as I did with WRF 3.2.1.
The one that run through, the wrfout_d01 files contain (by ncdump -h)
MMINLU = "USGS"
NUM_LAND_CAT = 24
but in wrfout_d02 and wrfout_d03 files, they show:
MMINLU = ""
NUM_LAND_CAT = 24
In the original wrf.exe.log file, if you have noticed, there are
INPUT LandUse = "USGS"
LANDUSE TYPE = "USGS" FOUND 33 CATEGORIES 2 SEASONS
WATER CATEGORY = 16 SNOW CATEGORY = 24
INITIALIZE THREE Noah LSM RELATED TABLES
LANDUSE TYPE = USGS FOUND 27 CATEGORIES
INPUT SOIL TEXTURE CLASSIFICAION = STAS
SOIL TEXTURE CLASSIFICATION = STAS FOUND 19 CATEGORIES
Why here has a 33 and 27 categories. but From my met_em files,
I tried your suggestion, both WRF 3.2.1 and WRF 3.2 stopped as before.
I appreciate your time and your insight.
