Log full of [Note] InnoDB: ft_end() after upgrade to MariaDB 10.3.10 My upgrade path was MariaDB 10.2.18 to MariaDB 10.3.10.

There are no bugs reported on mariadb or mysql bug tracker (at least that I could find).

Seems to be a rather meaningless info message. It certainly isn't an error or something to worry about.

It is a bit noisy and goes against a principle of the error log being quite clean (and meaningful). I recommend submitting a bug/pr to remove this line of code.
