Strange console log entries after enabling IPv6

[TomS]

Hi there,

yesterday, I enabled IPv6 on my FreeNAS box.
And since that time, the following messages keep being logged to the console and also sent by mail.
I have no idea how to stop them or whats the problem...
Could anyone help, please?

The error messages are like this:

Code:

Mar  9 20:00:47 NAS ntpd[83109]: bind(24) AF_INET6 xxxx:xxxx:xxxx::x#123 flags 0x11 failed: Can't assign requested address
Mar  9 20:00:47 NAS ntpd[83109]: unable to create socket on em0 (4) for xxxx:xxxx:xxxx::x#123
Mar  9 20:00:48 NAS ntpd[83109]: bind(30) AF_INET6 xxxx:xxxx:xxxx::x#123 flags 0x11 failed: Can't assign requested address
Mar  9 20:00:48 NAS ntpd[83109]: unable to create socket on em0 (8) for xxxx:xxxx:xxxx::x#123
Mar  9 20:05:48 NAS ntpd[83109]: bind(28) AF_INET6 xxxx:xxxx:xxxx::x#123 flags 0x11 failed: Can't assign requested address
Mar  9 20:05:48 NAS ntpd[83109]: unable to create socket on em0 (9) for xxxx:xxxx:xxxx::x#123

Best regards,
Tom

oh boy!
Sorry for the confusion, I found the cause of this issue.
There was a duplicate IPv6 address in the network.
