Hello list,
i had a crash at weekend with no apparend cause.
The aria engine did a recovery without furture problems.
Maybe that is a hint that somebody can make use of.
Hints welcome.
CU
from log:
230416 7:20:17 [ERROR] mysqld got signal 11 ;
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.
Server version: 10.5.15-MariaDB-0+deb11u1-log
key_buffer_size=134217728
read_buffer_size=131072
max_used_connections=86
max_threads=252
thread_count=38
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 685818 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...
