That makes no sense to me.  I don't know how you can make a TCP socket
have two IP addresses but not be bound.  Perhaps it is a socket in the
TCP state Close-Wait, or shut down by the other host and waiting for
a local close() system call.  A glut of such sockets could be caused
by a missing close() in some error path somewhere.

What was that about? 
Did whatever it was include any syslog complaints from dccm?
