The backtrace is from shutdown cleanup as pointed before, so it is not the one that caused the crash.
To get more than one core file, so it is not going to have core file overwritten, you have to enable one core file per pid/process (or set core file name pattern), some hints at: - https://www.kamailio.org/wikidocs/tutorials/troubleshooting/coredumpfile/ Searching on the web should reveal other tutorials about it. Then you should get more than one core file on a crash and you should grab the backtrace from all of them. You should also install the debugging symbols for libssl and libcrypto, there could be useful details shown in the backtraces.
