What is the value of errno?

Check the usual suspect: /etc/resolv.conf
If that does not help: there have been changes to the resolver code
between 3.7 and 3.8 as well. One thing is does is checking if
/etc/resolv.conf has been changed and then reload things. We need
more info to see what is going on. OB
Compiling the resolver code with -DDEBUG and enabling debug by
including options debug in resolv.conf can give a clue.
Or ktrace the process.
