 The message means that 74.125.178.18 is asking for the qname '
http://www.hospitalalemao.org.br' which obviously is malformed as the
characters ':' and '/' are not allowed in DNS and hence PowerDNS is
responding with a SERVER FAILURE message.
Usually bad code is responsible for malformed queries like that.
Usually not much you can do about it unless you are also in control of
these clients.
