[SR-Users] Kamailio 5.2.3 segfaulting

yes tls is loaded before db_mysql, is that bad?

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.
