some additional information: the Knot-DNS version running at the time
was 2.0.0-r1. It has since been updated to 2.0.0 (the release version).
The weird behavior seen might have been an artifact of the
release-candidate version.

I'm keeping an eye on the server and will try to gather more debug
information should something similar happen again.

Best regards
