BIND 8 data loss problem

[Kevin Darcy]

It's not recursing to itself; it's recursing to the authoritative 
servers (woodaa and woodab) for the child zone (wood). I'm not sure how 
you expect your server to provide the information when it has no 
authoritative data for the zone and recursion is disabled. As I said 
previously, if you don't want to recurse, then your most straightforward 
alternative option is to become a slave for the child zone. Then you'll 
be able to answer those queries directly from authoritative data.
