Description
2023-09-02 20:42:42 0 [Note] InnoDB: A semaphore wait:

Mutex at 0x55e8cc71c080, Mutex LOCK_SYS created ./storage/innobase/lock/lock0lock.cc:461, lock var 2
InnoDB: Pending reads 0, writes 0
2023-09-02 20:42:42 0 [ERROR] [FATAL] InnoDB: Semaphore wait has lasted > 600 seconds. We intentionally crash the server because it appears to be hung.

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: 10.5.19-MariaDB-0+deb11u2-log source revision: f8a85af8ca1c937b8d4f847477bd282f80251cde
key_buffer_size=134217728
read_buffer_size=131072
max_used_connections=152
max_threads=153
thread_count=154
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 467880 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...
