Memory-related error encountered while running 4dvar.

Hello,

I can run the 4dvar case in the official tutorial case, but there are always some memory-related errors when I run my case.I used a very small example to verify whether it was due to limited memory, so I used the area of 70*50*43, and the assimilation window was only 5 minutes. Problems still occur.Can someone help me?
The following is what my single-core runtime command line interface shows.

Here is the rsl.error.0000 .

When I use mpirun, the error has changed. The following is the command line display of mpirun -np 12 ./da_wrfvar.exe and the rsl.error.0000 file.

Does it need some special settings in the real.exe namelist.input, or anything can't set ?Here's my namelist.wps and namelist.input with wps.exe nad real.exe .
