I got lot's of crashes after upgrading from 9.16.18 to 9.16.19 too.
In my case it happened on Linux instead of FreeBSD though.
After reporting an issue (#2841) at gitlab.isc.org it turned out that there is a
already known problem which ought to be adressed in the August release. The
issue is marked as confidential though.

Just guessing, but maybe this will fix the crashes you are seeing as well.
