Host : OpenVZ 7 (7.0.18)

Description
Good evening!
Long story short: MariaDB randomly crashes after being restored (using a backup) and having its memory state restored by CRIU.
Command that triggers the bug: "vzctl resume <ctid>"
—
MariaDB 10.9.3 is installed inside an OpenVZ 7 container (Debian 10).
When resuming/restoring this CT using OpenVZ 7 commands, MariaDB sometimes crashes inside the container (mysqld got signal 8)"

Please find attached MariaDB "error log", "gdb log" and "config CT" (contains all commands to reproduce environment).
If needed, I can also provide CRIU "dump.log", "restore.log" and MariaDB core dump (246 Mo).
Have a great evening!
