I am having some issues migrating from my older bind servers to newer, secure cache & djbdns servers. If I attempt to ping inside my network to any address that resolves (local domains for which I host the dns records for) from Server C & Server D, its real slow :confused:. If I ping outside of my network everything is fine.
Server A & B - dnscache - 172.16.3.10 (cs1.inetdevspace.com) | 172.16.3.11 (cs2.inetdevspace.com)
dnscache listens on network interface and forwards all requests for local domans to Servers C&D. Any requests for domains that are not local go directly to root servers.
Server C & D - djbdns - 172.16.3.12 (ns1.inetdevspace.com) | 172.16.3.13 (ns2.inetdevspace.com)
Here are some inetdevspaces of the problems with time stamps that show how long its taken to ping.

If I issue the switch "-n" behind ping (Numeric output only. No attempt will be made to lookup symbolic names for host addresses.) everything works properly. I've also noticed that sending email is taking longer and longer.
This is what my data file looks like.
