I am running a master/slave bind 9.16.18 config on FreeBSD 11-Stable.
This also implements split horizon for internal and external hosts.

Periodically, the slave just stops properly resolving hosts properly, so I
turned on debugging and could use some help understanding messages I am

Could some kind soul explain the significance of the following
( is the public IP of the DNS slave instance):

07-Jul-2021 14:28:01.666 security: debug 3: client @0x8045f9160 ( view internal: reset client

07-Jul-2021 14:19:01.556 security: debug 3: client @0x8045f9160 ( view internal: request failed: duplicate query
