Lot of traffic after installing bind 8.4.3 on sparc

[bind8 mailinglist]

Hello Group

I encountered the flowing problem with the new version 8.4.3 of bind. Maybe 
someone have an idea what is going wrong?

After installing the new version everything went fine. The server gave 
answer. But afterwards we discover heavy traffic on our network.  

11:20:27.450179 IP our.name.server.53 > xxx.168.44.1.53:  41698 [1au] AAAA?

... a lot of traffic! Afterwards we changed back to 8.4.2 and everything 
went normal. 

The system is a `SunOS dns1 5.8 Generic_108528-24 sun4m sparc 
SUNW,SPARCstation-5`.

The changelog say something about ipv6 addr. and AAAA requests...

Any suggestion would be welcome.

Thx and by
