Debug information. The requested record was found.
% DATASRC_MEM_SUPER_STOP stopped at superdomain '%1', domain '%2' is empty
Debug information. The search stopped at a superdomain of the requested
domain. The domain is an empty nonterminal, therefore it is treated as NXRRSET
case (eg. the domain exists, but it doesn't have the requested record type).
% DATASRC_MEM_SUPER_STOP stopped as '%1' is superdomain of a zone node, meaning it's empty
Debug information. The search stopped because the requested domain was
detected to be a superdomain of some existing node of zone (while there
was no exact match). This means that the domain is an empty nonterminal,
therefore it is treated as NXRRSET case (eg. the domain exists, but it
doesn't have the requested record type).
