I thought so, too.

But the resolv.conf is functionally identical to those in the other Mandriva 
installs on the same LAN. (only the comments were different.)  Nameservers 
are pingable, fast, and name resolution works.  

The pause continues on machines where this ons can get a PTR in miliseconds.

I'll shut off some services and get a tcpdump tomorrow night.  This box was 
forced into early production after a HDD failure just before Christmas.

Previous testing with ethereal shows no packets between ACK and the service's 
banner many seconds later.
