xfer-in error failed while receiving responses: not exact
Description
I have upgraded my secondary DNS server from 9.18.5 to 9.18.6. The primary is 9.18.5. As a result I now receive a couple of error messages: xfer-in: error: transfer of (various domains from master) failed while receiving responses: not exact
A singe non-DNSSEC domain does not generate the error.
Request
A more useful error message.
