241006 14:40:32 [ERROR] mysqld got signal 6 ;

Sorry, we probably made a mistake, and this is a bug.

Your assistance in bug reporting will enable us to fix this for the next release.

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: 11.7.0-MariaDB-debug-log source revision: 77be73c489fb7c21ca58e78cef10e0c166f293d8

key_buffer_size=1048576

read_buffer_size=131072

max_used_connections=1

max_threads=153

thread_count=1

It is possible that mysqld could use up to 

key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 64017 K  bytes of memory

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

Thread pointer: 0x62c0000c0218

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...
