There is a problem reported with MariaDB version 10.4.x and MythTV:
https://jira.mariadb.org/browse/MDEV-20261
Maybe this is the cause of the problems reported in this thread.

I did a network capture and I see the same thing.
The crash happens only when i watch a program with no information on the grid TV (program unknown). Another clue is when mariadb crashes, mythbackend lets a empty ts file in its home directory, not in the storage group directory. I tried to debug, but it's too hard. I give up.

If you are using MariaDB version 10.4.x then I suggest to change to an older, 10.3.x, version of MariaDB, or to change to MySQL.
MythTV does rely on a correctly working database and when the database crashes on its own this is not something that can be fixed in MythTV.
When the MariaDB bug is fixed this will be noted in the Jira ticket referenced above and then also MariaDB version in which the fix will be implemented will be known.
You might also consider changing to a less bleeding-edge distribution such as Fedora or Ubuntu.
