You won't get much from wireshark, dig is complaining about the
connect() function and there being something wrong with one of the
arguments. The 22 is the error code and the part after the slash is the
error message matching 22. It is possible that the socket being used is
of the wrong type for the address being connected to. If the socket
opened is an IPv6 socket and the obtained address for the nameserver
being queried happens to be an IPv4 address you could get this behavior.
Does bindserver6 have an A address as well as an AAAA address for the
nameserver?
