> I have a very strange problem with a Bind server version 9.2.5 on Fedora
> Core 3.
> Named listen to one IPv4 address and any IPv6 address. The configuration
> has been running for many months. No changes where made recently to the
> configuration except for adding or removing slave zones.
> The symptom is that the server does not answer request to the IPv6
> address + port UDP 53. It still answers requests to the UDP and TCP port
> 53 using IPv4 and to the TCP port 53 using IPv6. Using dig on the
> server, or on any server on the same LAN, leads to the following behavior :
> - dig ns some.domain @IPv4-address : works fine
> - dig +vc ns some.domain @IPv4-address : works fine
> - dig +vc ns some.domain @IPv6-address: works fine
> - dig ns some.domain @IPv6-address: works once or twice immediately
> after restarting named, fails afterwards
> The logs show the following message :
> Jan 16 23:34:25 named: failed to get request's destination: failure
> Jan 16 23:34:27 named: client.c:1325: unexpected error:
> I had a look on client.c around line 1325 but it didn't help much.
> Does someone on the list have an idea on what's wrong ?
> Thanks very much in advance.

Run 9.3 or 9.4. They both handle IPv6 a lot better than
9.2 especially with Linux's broken IPv6 stack.
