How exactly do you run the nslookup (also please use dig instead of nslookup for debugging)? It’s hard to help without full diagnostics. Looking at pcaps (or using Wireshark) to look what happens on the wire when the failure occurs would help. You can also run named with extra debugging level to provide more insight.
