HiYour namelist.input looks fine to me. The message "Tile Strategy is not specified. Assuming 1D-Y" is normal and it doesn't suggest any issues.
Can you find other error messages in your rsl files?
How did you compile WRF and run this case?
Thank for your qiuck reply.
Another pronlem is:
*** Error in `./wrf.exe': free(): invalid pointer: 0x000000001fbf27f0 ***
Program received signal SIGABRT: Process abort signal.

I compile the wrf using GNU Fortran 7.3.1.
I use one core with 24 ntasks to run this case.I attch the wrfrun.sh at attachment.
Thanks again!

Such information is not helpful at all. Please provide more information regarding this case:
(1) Which version of WRF did you use?
(2) The data you ungrib to drive WRF
(3) How long did the model run before it crashed?
(4) Can you run the case over a single-domain?
(5) with num_land_cat = 33, what landuse type did you specify ?

(1):WRF4.2
(2):I ungrib the NECP fnl data to drive WRF
(3):It was decided the nest.If i was use three nests,it will cresh at the first timestep.One or two will run more time and then cresh.
(4):I can run the case over a singe_domain
(5):The 31-33 respectively represent Low density residential, High density residential and Commercial.
Now,i modify cudt=0 and feedback=0.After the change, i can smoothly run the case!
Thank you again for you response!
Thank you for the detailed information, which clearly indicates that this is a memory issue, i.e., when you run this case over muitl-nested domains, your machine memory is not large enough.
Please increase the number of processors, which will give you larger memory to run the case. If this case still fails, please consult your computer manage to get larger computer memory.
