F.Y.I. If you are obfuscating names, please use (fairly) well documented 
documentation domains.  "example.com" (like you have) or "example.net" 
or "example.org".  The same goes for IPs, 192.0.2.0/24 - Test Net 1, 
198.51.100.0/24 - Test Net 2, and 203.0.113.0/24 - Test Net 3.  ;-)

Presuming that the problem is not configuration related, I would 
immediately wonder if there is something in the network that is 
preventing the transfer of the problematic zone.

How big (# of RR) is the zone that transfers properly?  What about the 
problematic zone?

I'd probably go for TCPDump and / or Wireshark to analyze the transfer 
that is failing.  You will probably want to check both ends.  It would 
be really nice if you can capture from both ends at the same time to 
compare them.

I half way expect that something is different about your problematic 
zone.  Either you can't successfully send large (> 512 Byte) queries / 
responses, or TCP is filtered.  This would be evident by the server end 
sending the data but the receiver not seeing it.
