Please refer to https://mariadb.com/kb/en/how-to-produce-a-full-stack-trace-for-mysqld/ 240215 23:10:14 [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: 11.1.4-MariaDB-1:11.1.4+maria~deb12 source revision: b6680e0101c1e3cde9f0d7496443db1277064e84 key_buffer_size=134217728 read_buffer_size=131072 max_used_connections=49 max_threads=153 thread_count=49 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 468063 K bytes of memory Hope that's ok; if not, decrease some variables in the equation.
