Hi,

I had a bit of a search in https://jira.mariadb.org and didn't see any
obvious things reported that indicate its known or fixed.

A cleaner backtrace with debug info packages and the core file
generated (if possible/reproducable) would be of assistance.
debuginfo: https://mariadb.com/kb/en/how-to-produce-a-full-stack-trace-for-mysqld/#installing-debug-info-packages-packaged-by-ubuntu-or-debian
full backtrace:
https://mariadb.com/kb/en/how-to-produce-a-full-stack-trace-for-mysqld/#analyzing-a-core-file-with-gdb-on-linux

Also the "SHOW CREATE TABLE messwerte" information would be useful in
identifying features that might have contributed towards this bug.

How long have you been running 10.5.15 and inserting into this table?
Was there a previous version you ran? Did this problem occur then?

Does dmesg show any kernel or filesystem errors?

Further information in a bug report https://jira.mariadb.org or here welcome.

Daniel Black
