      Description

      Hello,

      After I installed a new server with MariaDB 10.4 or 10.5, I am facing on ubuntu syslog the "systemd[1]: mariadb.service: Main process exited, code=killed, status=11/SEGV" being reported a lot of times.

      Then applications loss the DB connections and some transactions are broken. I tried to install a new server, MariaDB, and restore a existing mysql dump file, however the same error happened.

      My system: - AWS EC2 running ubuntu 18.04 instances; - MariaDB 10.4.14 / 10.5 (error on both versions); - Client applications (nodejs using mysql or mariadb dependency);

      My findings so far is that only on MariaDB 10.4.13 (using a not-upgraded developer server and another one using AWS RDS MariaDB) the error does not happen.

      All other tentatives, I tried existing and new servers with MariaDB 10.4.14 and 10.5.x, the erratic behavior was the same (service crash and restart with status=11/SEGV).

      I am attaching my syslog and coredump files.

      PS: I also recorded the error on community KB:

      Best regards,
