Occasionally I will look the "lame-log" on one of my BIND 9.6.1-P1
servers and find FORMERR messages. Then I do DNS queries to try to
understand why the FORMERR occurred. Here is one where I am confused:
03-Dec-2009 16:07:50.722 lame-servers: info:

The response to the query for the "A" record looks fine, as does the
AAAA query response. Why the FORMERR? Thanks.
