Caught signal 11 (Segmentation fault: address not mapped to object at address 0xfffffff8055de170)

Hi everyone！
I was running wrf-chem with real.exe succeed , and there are no errors occured.
But when it comes to wrf.exe , I have met some Segmentation Fault.
No matter how many cores I use (from 6 to 192) , the fault keep coming out.
I have no idea about this . I attach my namelist and the rsl.error file here.
Could anyone can help me please?

Hi,
Apologies for the delay. Can you compile wrf WITHOUT chemistry and try to run this? We need to know if this error is specific to the chemistry code, or to basic WRF. If you run basic WRF (with a non-chemistry compile, and no chemistry options turned on in the namelist), and it still fails, please attach the updated namelist.input file, as well as all of the rsl files (packaged together into a single *.tar or zipped file).

I have run WRF-Chem successfully by simply reducing the core number. Also thank you for your reply!!
Now, I have another question:
I have seen someone use dust_opt=15, and there is no infomation about this in User's Guide. So what is this option represent for? Also, is there any other option like this, like dust_opt=11,12,13 or 14?
Please tell me how can I get the introduction of those option!!! Really hope for your answer, thank you.
