This definitely shows a problem. Either there is something else running
and binding to the wildcard IPv6 socket or there is a problem with
support of IPv6.

Something is preventing it from binding to the IPv6 wildcard socket. You
should see a line like this in the netstat output for udp6:
udp6 0 0 *.123 *.*
The actual line depends on the O/S. The above is from FreeBSD.
Do you have other applications on this system using IPv6?
