 What packet resulted in AUTH_PACKET_PARSE_ERROR?

 Getting around 17000 queries per second so hard to know. I got this error
 984 times in about 11 seconds. (1000 SERVFAILs were sent.)

 Documentation has:

 {{{
 AUTH_PACKET_PARSE_ERROR unable to parse received DNS packet: %1

     This is a debug message, generated by the authoritative server when an
 attempt to parse a received DNS packet has failed due to something other
 than a protocol error. The reason for the failure is given in the message;
 the server will return a SERVFAIL error code to the sender.
