Hi Daniel, So our DB is in rds and this is what I can gather:
+-------------------------+------------------------------+
| Variable_name | Value |
+-------------------------+------------------------------+
| innodb_version | 5.6.34 |
| protocol_version | 10 |
| slave_type_conversions | |
| version | 5.6.34-log |
| version_comment | MySQL Community Server (GPL) |
| version_compile_machine | x86_64 |
| version_compile_os | Linux |
+-------------------------+------------------------------+
The mysql server/client library we received from my apt-cache madison output earlier.
I don't know if upgrading to 20.04 is an option.
Given this said, what are the symptoms of these crashes? I'm guessing one of them is a brief disconnect from the DB for dialplan/dispatcher/carrierroute lookup?
Thanks.

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.

Is this crash due to libcrypto or mysql client? Currently I have the following mysql client installed on the kamailio instance:
ii lib*mysql*client20:amd64 5.7.34-0ubuntu0.18.04.1 amd64 MySQL database client library
ii *mysql*-client 5.7.34-0ubuntu0.18.04.1 all MySQL database client (metapackage depending on the latest version)
ii *mysql*-client-5.7 5.7.34-0ubuntu0.18.04.1 amd64 MySQL database client binaries
ii *mysql*-client-core-5.7 5.7.34-0ubuntu0.18.04.1 amd64 MySQL database core client binaries
ii *mysql*-common 5.8+1.0.4 all MySQL database common files, e.g. /etc/*mysql*/my.cnf
