Hi Bernhard,
Thank you for replying.

Hello Anton Avramov,
not involved in packaging of isc-kea I just read
your report and may have some points.
Why do you use the upstream binary of libmariadbclient.so.18.
Is the stretch packaged version 10.1.37-0+deb9u1 too old? [1]
Yes. We are using mariadb 2.10 for our implementation across hundreds of
installations. We don't have problems with the other services connecting
to mariadb using the installed libmariadbclient
And it looks like you installed the debug symbol package
kea-dhcp4-server-dbgsym?
Maybe you could also add kea-common-dbgsym?
And if it fails with libmariadbclient18 from stretch also
I would have suggested to install libmariadbclient18-dbgsym,
but unfortunately it looks like there are no debug symbols from
security packages broadly available [2].
OK. I've installed libmariadbclient18-dbgsym from the upstream packages
with the corresponding libmariadbclient18 package.
Here is the result:

(Maybe a set of local rebuilt packages for 10.1.37-0+deb9u1
including the dbgsym package?)
