WRF V4.2.1 - The domain size is too small for this many processors

Hello,

I have encountered the following error while running wrf.exe:

For domain 1 , the domain size is too small for this many processors, or the decomposition aspect ratio is poor.

Minimum decomposed computational patch size, either x-dir or y-dir, is 10 grid cells.

e_we = 93, nproc_x = 4, with cell width in x-direction = 23

e_sn = 68, nproc_y = 7, with cell width in y-direction = 9

--- ERROR: Reduce the MPI rank count, or redistribute the tasks.
-------------- FATAL CALLED ---------------
FATAL CALLED FROM FILE: <stdin> LINE: 2385
NOTE: 1 namelist settings are wrong. Please check and reset these options
-------------------------------------------
application called MPI_Abort(MPI_COMM_WORLD, 1) - process 0

I was using 24 processors for this run. You can find namelist.wps and namelist.input files attached.

Any help or guidance would be highly appreciated. Thanks in advance.
