- % RESLIB_OPCODE_RESPONSE response to query for <%1> did not have query opcode
- A debug message, the response to the specified query from an upstream
- nameserver was a response that did not have the opcode set to that of
- a query. According to the standards, this is an invalid response to
- the query that was made, so a SERVFAIL will be returned to the system
- making the original query.
- % RESLIB_PROTOCOL protocol error in answer for %1: %3

- the specified <name, class, type> tuple in the cache. The instance number
- at the end of the message indicates which of the two resolve() methods has
- been called.
- % RESLIB_RECQ_CACHE_NO_FIND did not find <%1> in the cache, starting RunningQuery (resolve() instance %2)
- This is a debug message and indicates that the look in the cache made by the

- % RESLIB_RRSET_FOUND found single RRset in the cache when querying for <%1> (resolve() instance %2)
- A debug message, indicating that when RecursiveQuery::resolve queried the
- cache, a single RRset was found which was put in the answer. The instance
- number at the end of the message indicates which of the two resolve()
- methods has been called.
