After upgrading to mariadb: 10.6, a server crash may occur.
The server crash is related to the change from d_flush to o_direct when using the BTRFS filesystem, I suppose a similar problem may occur with ZFS but here I have no official confirmation.

To suppress the problem, you need to change the configuration in the database engine itself, but this has an impact on performance.
Finally, according to the men from MariDB, the correct elimination of the problem with Mariadb is:
Upgrade to version 5.18 and update MariaDB to a version equal to or above 10.6.8 (Current 10.6.10 GA)
