      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.

      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.

            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: 10.7.0-MariaDB
            key_buffer_size=134217728
            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 = 467956 K bytes of memory
            Hope that's ok; if not, decrease some variables in the equation.

            where mysqld died. If you see no messages after this, something went

            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: 10.7.0-MariaDB

            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 = 467956 K bytes of memory
            Hope that's ok; if not, decrease some variables in the equation.
