    XMLWordPrintable

Details

    • Can result in hang or crash
    • InnoDB could crash if the parameter innodb_buffer_pool_size_auto_min was set and it failed to shrink the buffer pool in response to a Linux memory pressure event.

    Description

      We have a number of mariadb systems on which an overnight database-check script runs.
      On one of them, which has a smaller amount of RAM but compensating larger swap size the mariadb process crashes overnight
