Hi Daniel,
I just confirmed mysql is compiled using libssl.so.1.1.
As for the other kamailio packages, I only see two that are installed where
both are depends on libssl1.1
kamailio-tls-modules:amd64
*Depends*: kamailio (= 5.4.5), libc6 (>= 2.14), libcurl4 (>= 7.16.2),
libssl1.1 (>= 1.1.0)
kamailio-websocket-modules:amd64
*Depends*: kamailio (= 5.4.5), libc6 (>= 2.14), libssl1.1 (>= 1.1.0),
libunistring2 (>= 0.9.7)
So in my case here there shouldn't be any conflict with mysql client libssl
version?
Thanks.

Hello,
I think the relevant here are the client library. I asked about mysql vs
mariadb because some distro had (meta-)packages named mysql but installing
mariadb. Debian at some point switched to something like
default-mysql-client...
Based on backtrace, the crashes would prevent kamailio to start, as
carrierroute_db_open() is used in mod_init/child_init callbacks.
A variant you could try is the use of mysql-proxy to bridge from a local
unix socket to remote mysql, so kamailio connects to mysql server via
local unix socket and by that won't use libssl.
First you can check with ldd if mysql client libraries are compiled
against libssl1.1 and the libssl1.0 is also used for other packages.
Cheers,
Daniel

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.
Cheers,
Daniel

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
root@ashintgtpsg51:/var/lib/cores # apt-cache madison mysql-client
mysql-client | 5.7.34-0ubuntu0.18.04.1 |

Any suggestions would be greatly appreciated.
