    Details

      Description

      AWS RDS MariaDB 10.5.9 crashes with signal 11 consistently upon SELECT query below.

      Rebooting and increasing memory does not help. Any ideas?

      210728 22:04:30 [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: 10.5.9-MariaDB-log
      key_buffer_size=16777216
      read_buffer_size=262144
      max_used_connections=31
      max_threads=75
      thread_count=32
      It is possible that mysqld could use up to
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 190955 K bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.
