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: 10.11.3-MariaDB-1:10.11.3+maria~deb11-log source revision: 0bb31039f54bd6a0dc8f0fc7d40e6b58a51998b0
key_buffer_size=134217728
read_buffer_size=131072
max_used_connections=4
max_threads=153
thread_count=4
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 468022 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
Thread pointer: 0x7fd3f4001668
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...
