emerge info from the host

same problem here, which results in an incredible slow lookup performance.

Sorry guys, I didn't notice this bug before :/
Is it still persistent with 9.4.3_p5?

I just wanted a answer to my question.

[Comment 8 Christian Ruppert (idl0r) 2010-11-10 18:51:13 UTC]

It doesn't really use IPv6, it just reads the config values + default values. In this case it is "use-v6-udp-ports". It also doesn't listen on any IPv6 addresses or interfaces.
To me it looks like they just didn't check for IPv6 support when setting the default values or the default internal zones.
So it doesn't ignore the ipv6 useflag.

For "max open files" take a look at bug 296663.
