shared IPv6 doesn't work as expected

I’m running my server dual stack. In my configuration I use shared IPv4 and a corresponding shared IPv6.

after trying to access my site on IPv6, I got the default interworx page and not the domain I requested.

I get these error when I restart httpd
Stopping httpd: [ OK ]
Flushing IPC Semaphores [ OK ]

{IPv6} is 1 IPv6 IP address (censorred)

Does more people have this problem?
