    Description

      MariaDB server crashed without any apparent reason.

      In MariaDB errorlog there is:

      double free or corruption (!prev)
      210618 11:20:31 [ERROR] mysqld got signal 6 ;
      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: 10.3.27-MariaDB-0+deb10u1-log
      key_buffer_size=134217728
      read_buffer_size=131072
      max_used_connections=44
      max_threads=152
      thread_count=50
      It is possible that mysqld could use up to
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 465226 K  bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.
       
      Thread pointer: 0x7f3428000c08
      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...
      stack_bottom = 0x7f34b2a7edd8 thread_stack 0x49000
      

      The DB server became unresponsive, but in init.d mariadb process status was OK.
