I noticed that, too. But I found it strange, that the first attempt failed.
I don't know whether it is worth the effort to fix this kind of issue, which
might not be severe, but fills the logs with obscure entries. Besides, I
got used to solve issues with some machines by doing it in the order of
their precedence, as often the dependency of some issues is totally obscure.

By the way: I find Bind being pretty stable. To the best of my knowledge
the last versions of Bind primarily fixed security issues, which I would not
expect to be the primary concern here, as I presume that server won't be
exposed to the internet. So I would not expect too much from upgrading
I only have a small network, and I use fixed IP addresses for all my
machines. At least in that scenario I never observed an issue with
"forgotten" DNS entries. What I observed some time ago was, that the
link between Bind and Samba had been broken, but apparently Bind did
continue to use cached information from before.
But after a clean resinstall everything works as it should.
HTH & Best regards
