Henning,
I can't find anything else. But I caught one more segfault in the same
scenario (stopping service)...
Program terminated with signal SIGSEGV, Segmentation fault.

Richard,
I start service with the following parameters
/usr/local/sbin/kamailio --atexit=no -m 256 -P /var/run/ser/kamailio.pid -u
ser -g ser -f /usr/local/etc/kamailio/kamailio.cfg -w /usr/local

Can you try with
kamailio ... --atexit=no ....

And yes, the problem is definitely related to FIPS, because I did not see
any errors with regular OpenSSL 3.x.

Hello Henning,
yes, I use this major version
$ openssl version
OpenSSL 3.0.7 1 Nov 2022 (Library: OpenSSL 3.0.7 1 Nov 2022)
Thanks, I'll try updating Kamailio and report the results.

Hello,
are you on openssl 3.x by any chance? If yes, please upgrade to
kamailio 5.7.5 or 5.8.1 and set tls_thread_mode=2 in the kamailio.cfg, as
it fixes certain memory corruption issues on this openssl version.
If you are still getting crashes after the upgrade and setting, please
let us know, it might be something related to the FIPS mode.
Cheers,
Henning
