MythTV 31.0 crashes mariadb 10.4.13 when trying to play LiveTV or Record

[Andrew Meredith]

After an upgrade from MythTV 0.29 and MariaDB 10.1.26, including

• Running the mariadb upgrade tool
• Seeing the database schema upgrade through

The mythfilldatabase run works fine. The Schedule displays correct information.

But any attempt to collect new episodes results in a MariaDB crash and a return to the previous screen with no messages in mythfrontend.

I can see from strace that mythbackend doesn't even get to the part where it opens the capture device, it drops the attempt while setting up the recording when the entire database service crashes.

First, I'll point out that you seemed to ignore the explicit instructions to not change the priority/severity (that is for the project team to decide).

Second, this sounds like the well known mariadb issue with 10.4.x where x is less than 14 (and 10.5.y where y is less than 4 as I recall). Upgrade your mariadb version (which may require you to work with your distro provider if you are not capable of doing the work yourself).

To the project maintainers: I would suggest that this ticket should be closed as an upstream issue. Refer to mariadb bug MDEV-20261

To the original reporter, please follow Gary's suggestion to upgrade MariaDB.
