yes tls is loaded before db_mysql, is that bad?
Not, tls before any other modules potentially using libssl is the right order.
Yes apt updates were run so could have been updates to anything. OS version is 16.04.6 LTS (GNU/Linux 4.4.0-1098-aws x86_64) Updates we last run a couple of weeks ago.
Upon further digging I think the tls change was released a couple weeks ago so yes probably unrelated.
Install the packages with debug symbols for kamailio, libmysqlclient and libssl/libcrypto, then grab again the "bt full", it should show more details in the backtrace that may help to identify the issue.
Cheers,
Daniel

The issue seems to come from libmysqlclient library, not to kamailio handling sip traffic over tls.
Is tls module loaded before the db_mysql module?
Have you made other updates to the operating system? Or only the change you mentioned about server requiring and verifying certificates?
What version of ubuntu do you run?
I see that it uses libssl 1.0, so it is no relation with the change in libssl 1.1 internal api.

Daniel

Locate it and send the full backtrace with gdb from it.

I'm sorry you are correct, the version we are running is 5.2.5. I've just run ulimit -c unlimited to hopefully get a core dump next time since I don't see one in /var/lib/systemd/coredump/. Not sure if there is anything I need to do to get a coredump.
The log just shows:

If you use the repo listed at http://deb.kamailio.org/ , then it should be 5.2.5, and there is also option to install 5.2 branch debs built nightly.

Hello,
that log message is irrelevant for actual crash. Did you get core files? Or other log messages before the one you pasted?
You should upgrade first to latest 5.2.x, either 5.2.5 or latest branch 5.2.

I'm seeing this in the log and kamailio is crashing every hour or so:

Any ideas? Should I emergency upgrade to 5.3.1?
