Dear all,

I setup a Kamailio 5.5.0 (from GIT) on a ubuntu Ubuntu 18.04.5 LTS and I have some error with the libssl/ libmysql, seems not happening every time.

Regarding the config file, it’s a config running correctly on a Kamailio 5.3.x on a centos 7

I have attached the returned error and the result of the core file.

Any idea ?

Laurent
