Does not surprise me.  I have been getting some DNU errors over #remoteAddress or something.  I need to dig into it and make sure I didn't cause it.  It further happens only on timeouts, so it was a bit more elusive.
 
I'll bet that if you look into it, you will find code that is sometimes protected by #useOldNetwork and other times called without the test.  We really need to separate the IPv4 and 6 code with subclasses so that we can see what is related to what - at least that is how I have approched the little bit of work I've been able to do on this.
 
While I am rambling, suppose a name maps to many addresses, and the DNS server is doing round-robin distribution.  What should NetNameResolver do in that case?  It was always giving me one particular address - the one to a host that did not exist.  $10 says somebody was using a Microsoft security tool to improve our network ;)
 
On the lighter side: I think I just successfully built an RC1 image!!!!

A bit more on this, although I have not debugged any code yet.

Start a Pharo image with Seaside running on port 8080

1)

'http://127.0.0.1:8080/seaside' asUrl retrieveContents.

Works on Linux, but NetNameResolver throws a "primitive has failed exception on a Mac with the latest VM.



2)

'http://localhost:8080/seaside' asUrl retrieveContents.

Time's out in both Linux and Mac



3)

'http://www.google.co.uk' asUrl retrieveContents

Works in both platforms
