SIGSEGV error related to emissions?

Hi everyone!
I was running WRF-Chem3.9.1 with KPP, reinitialized the meteorology every 24 hours but with chemistry field from previous time step when doing re-initialization. After running several days, a SIGSEGV occurred (see all_rsl.error.txt attached). Since I found in the error log file there is warning message like "temperature too high at i=168 ,j=149 ;resetting to 315K" before the simulation stopped, I did several tests:
1) a test simulation with biogenic emission turned off, but it still failed with similar error (see no_bioemiss_rsl.error.txt)；
2) a test simulation with all emissions turned off, but it still failed with similar error (see no_emiss_rsl.error.txt)；
3) a test simulation without chemistry (using WRF only version code), and it ran successfully.

So I could only narrow down that some issues occurred with chemistry part, but I don't have any clue to further identify the issue. I hope you guys would help me and i appreciate it a lot.
Also attached is the namelist.input. I am using MEGAN for biogenic emissions and anthropogenic emssions are based on NEI.

Hello, I would like to ask you if your problem is solved, I am also experiencing the problem of excessive temperature stopping
 
Hi. It turns out my issue is related to sw/lw radiation scheme, and I can run through the simulations with RTTMG scheme.

Thank you for your reply, I've been using RRTMG scheme, but when I change the the chem opt that it doesn't work
 
Dear all,
I am also facing the same issue. For your information, I used the CBMZ-MOSAIC chemistry option and RRTMG as SW and LW radiation schemes. Can anyone please guide me to solve this issue?
With regards,
Ankan
