I'm using SuSE's bind-9.2.3-76.9 package from SLES9. I'm not certain as to
the correctness of my server's configuration -- but just knowing more
about this error (what is rdata? where is it read from? what
misconfigurations could make it unreadable?) would do a great deal of
good. Google has been quite unhelpful, hence my appeal to this list.

Many thanks, all!
