A customer has asked:

> We've come across an issue where we are trying to rndc addzone some
> zones with a lengthy list of servers to allow transfers and also
> notify.  We get an error back from rndc that we've exceeded the
> maximum length, even though these zones would be perfectly valid if
> added to the named.conf manually.  Would it be possible to increase
> the length allowed for an rndc addzone?

> Just curious if that is something easy to modify or if there was a
> reason for the limitation.  Thanks!
