[time 2025-07-16T11:57:09.054311] [level WARNING] [thread 52949] [sql_class.h:5238] Aborted connection 322 to db: 'test' user: 'root' host: 'localhost' (Got an error writing communication packets)

250716 11:57:09 [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: 10.6.10-MariaDB-debug-log
key_buffer_size=1048576
read_buffer_size=131072
max_used_connections=3
max_threads=65537
thread_count=1
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 25171359 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Thread pointer: 0x786ea8188c68
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...
