MariaDB 10.6.5
Description
I have very frequent database crashes on my server. All crashes are associated with the same error (InnoDB: Assertion failure in file /home/buildbot/buildbot/build/mariadb-10.6.5/storage/innobase/buf/buf0buf.cc line 2725). Crashes for different types of queries from different tables. Sometimes Systemd cannot restart MariaDB correctly. Similar behavior was before the complete reinstallation of the OS on the server (Debian 9, MariaDB 10.2/10.4)

211230 11:37:31 [ERROR] mysqld got signal 6 ;
|
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.

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