ER_FILSORT_ABORT triggers - crash query when "for update" in a select statement

Details

    Description

      Hi,

      MariaDb server crashes when a query like this is executed repeatedly:

      SELECT m.* FROM messenger_messages_fr1 m WHERE (m.delivered_at is null OR m.delivered_at < '2021-07-30 1
      1:35:00') AND (m.available_at <= '2021-07-30 12:35:00') AND (m.queue_name = 'mailer_async') ORDER BY available_at ASC LIMIT 1 FOR UPDATE

      Logs show this:

      0x7faff3f8f640 InnoDB: Assertion failure in file /var/tmp/portage/dev-db/mariadb-10.5.10-r1/work/mysql/storage/innobase/lock/lock0lock.cc line 6682
      InnoDB: We intentionally generate a memory trap.
      InnoDB: Submit a detailed bug report to https://jira.mariadb.org/

      I am using the Messenger component from Symfony, which runs this query, I detected that when 2 servers are connected to the same database, and run the same symfony command for mananing queues, when both commands try to lock the same row repeatedly, this error happens.

      This error is experienced both using a single database and multiple in a galera cluster setup.

            The "Sort Aborted" is a ER_FILSORT_ABORT error. This is caused by a disk write error during the file sort. Is there some OS cause here?

            Either way, the server shouldn't abort based on this condition.

            Thanks for the bug report.

            Hi,

            Here you are more detailed info, (1) logs and (2) my.cnf conf:

            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.

            Hope that's ok; if not, decrease some variables in the equation.

            Just for your info I there is a modification in the messenger table indexes, used by the Symfony messenger component. May have some relationship and could help you in some way:

            https://github.com/symfony/symfony/blob/4.4/CHANGELOG-4.4.md

            bug #42345 [Messenger] Remove indices in messenger table on MySQL to prevent deadlocks while removing messages when running multiple consumers (jeroennoten)

            Thanks

            The crash occurred in the expansion of the macro check_trx_state() in the function DeadlockChecker::check_and_resolve(). Thus, I think that this report duplicates MDEV-25594.
