(Reopen) Unexpected crash occured repeatedly

    Details

      Description

      Thank you for many people's previous support for my issue.

      After upgrading my DB from 10.2.8 to 10.2.24, unexpected crash has been occured again

      and DB left error log below.

       
      #######
      190621 16:39:39 [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.

      DB/Table configuration has no problem and the result of analyzing table may have no issue.

      ######
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 408925 Kbytes = 399.34Mbytes of memory
      Hope that's ok; if not, decrease some variables in the equation.

      My DB : 128M + (128K + 128K) * 1000 = 128M + 256M = 384M
      ######

      Any suggestion or advice is highly appreciated.

      If you want to get more information, please let me know.

      Thank you!

      Thank you and have a good day!
