MariaDB server crasesh when OPTIMIZING several tables (mysql_alter_table)

Details

    Description

      Hi,

      When I run mysqloptimize -A, MariaDB crashes. If I try to optimize the tables manually, one by one, it works fine. Only happens when I try to optimize several tables at the same time. I also tried with OPTIMIZE table1, table2, ... and it crashes.
      The tables can be empty (without data, only structure) and crashes.

      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: 10.9.3-MariaDB-1:10.9.3+maria~ubu2004-log
      key_buffer_size=268435456
      read_buffer_size=131072
      max_used_connections=2
      max_threads=502
      thread_count=2
      It is possible that mysqld could use up to
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 8564374 K bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.

            The posted stack trace is invalid. Can you please install the -dbgsym package and try to get a proper stack trace with GDB?

            The failing assertion is this one, hinting corruption of a ROW_FORMAT=COMPRESSED InnoDB table.

            	/* Ensure that each heap no occurs at least once. */
            	ut_a(i + PAGE_HEAP_NO_USER_LOW == n_heap);
            

            This assertion fails while a compressed page is being modified.

            Please be aware that MariaDB Server 10.9.3 was affected by the recovery bug MDEV-29383. Even if restoring a backup or recovering a crash seemingly succeeded, some log records might not have been applied, and therefore you could have a corrupted database. You should upgrade to 10.9.4 to prevent further corruption of that kind.

            Hi,

            I added the stack trace and the error log.

            I will upgrade to 10.9.4 as soon as I can download the compiled binary for Ubuntu (ubuntu repos).

            It is possible that this bug has been fixed by MDEV-29742. This was caused by MDEV-28457.

            From stack trace, it looks like it is a duplicate of MDEV-28797

            Hi,

            seems that the issue is still affecting the new version (10.9.4+maria~ubu2004)

            Attached new backtrace.

            xkill Pablo Catalina added a comment - Hi, seems that the issue is still affecting the new version (10.9.4+maria~ubu2004) Attached new backtrace.

            This is expected. See the Fix Version/s field of this issue — it says that the issue was fixed in 10.9.5.
            You can find the planned release date for 10.9.5 at https://jira.mariadb.org/
