Bind9 / Named Question

[C M Reinehr]

Thanks to all in advance!

I set up a new server last month -- Debian v8.5 (Jessie) -- running Bind9 (1:9.9.5.dfsg-9+deb8u5).
I copied the configuration files from an older server and everything seems to be operating normally
except for one irritating behavior.

I also am running logcheck and every hour of the day, day in & day out, I receive the following messages:

Always the same named domains. Some times fewer & some times more, but 24 hours a day these
messages are being logged.

Can anyone explain what program is triggering these attempts to validate these domains & why there
is a problem.

I have added the following statements in my named.conf.options file:

	dnssec-enable yes;

	dnssec-validation auto;

	dnssec-lookaside auto;

Originally, it contained only the statement dnssec-validation yes; Changing made no difference.

Cheers & thanks, again!
