This error recently showed up on a RHEL 3 Server running BIND v9.3.2

This machine is a mail server which is configured exactly the same as
another RHEL 3 except that BIND would not work for some reason. Finally got
it to work, only to get this error/bug.

This error/bug is reference in but I do not
understand the solution.

If anyone has any ideas much appreciated.
