10.5.9 crashes with large IN() list



    • Bug
    • Status: Closed (View Workflow)
    • Major
    • Resolution: Fixed
    • 10.5.9
    • 10.5.10
    • Optimizer
    • None
    • Centos 8 and Centos 7, phpbb 3.3.x


      I upgraded from 10.5.8 to 10.5.9 and a particular delete statement for phpbb 3.3.x cause MariaDB to crash.

      This is the statement:

      DELETE FROM phpbb3_notification_emails
                              WHERE notification_type_id IN (3, 4, 5, 6, 23) AND user_id = '5044' AND item_parent_id IN ('544', '53', '1939')

      (Note that the IN list is actually 4642 values long, the above has been truncated to 3 for ease of viewing)

      This only started happening once MariaDB was upgraded from 10.5.8 to 10.5.9. I believe that 10.5.8 had a bug fix itself to a similar issue


      So I wonder if 10.5.9 has a regression error?

      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
      It is possible that mysqld could use up to
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 104669 K  bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.
