There aren't repetitions among the elements of the chain. I use the pdns recursor as an authoritative server with one zone file. It's version is 3.3-3 on a Debian Wheezy. I also tried the +tcp option with the dig client but it didn't help.

PowerDNS limits the lengths of chains and other indirections. The limits do not follow directly from the DNS standards.

Why do you want to do this?
