Neither of those two is running. I've rebooted the machine. I cannot see
any caching outside of BIND9, and that should not be caching if it gets
the stuff from `bind-dlz` as you say.

I just ran `samba_upgradedns --dns-backend=BIND9_DLZ` and that seems to
have fixed the problem. Oh boy, I am glad.

Thanks for engaging with me!
