[SR-Users] Need help analyze crash

[Daniel-Constantin Mierla]

Hello,

did you upgrade the Kamailio only or also mysql server/client library?
Is it Oracle's MySQL or MariaDB?

A while ago, there were a few reports of problems with mysql-client
(Oracle) library on Ubuntu 16.04 and 18.04, which typically happened
after upgrades of the library, as I understood, the upgrade brought in a
dependency on libssl 1.1, while libssl1.0 was used by most of the other
packages, resulting in mixed deployments. Upgrading to 20.04 seemed to
solve it, as it came with libssl1.1 only.

Cheers,
Daniel
