This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
To report this bug, see https://mariadb.com/kb/en/reporting-bugs
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.

It is possible that mysqld could use up to

Hope that's ok; if not, decrease some variables in the equation.

The MariaDB-Docker-Image is derived from Ubuntu:bionic, it is the official image from Docker Hub.

Maybe relates to MDEV-21663, MDEV-21800, or MDEV-21787

Version 10.4.12 is not affected, if that helps.

Best regars, Jan
