stale: impossible condition

[Thomas Duterme]

Hi folks,

I reloaded my BIND server and found the following error
which I had never come across:

Dec 11 20:14:38 grendel named[10062]: reloading nameserver
Dec 11 20:14:38 grendel named[10062]: /etc/named.conf:18:
syntax error near '/'
Dec 11 20:14:38 grendel named[10062]: pri/51go.com: WARNING

Dec 11 20:14:38 grendel named[10062]: hint zone "" (IN)

Dec 11 20:14:38 grendel named[10062]: Ready to answer

Dec 11 20:15:17 grendel named[10062]: stale: impossible
condition
Dec 11 20:15:17 grendel named[10062]: stale: impossible
condition
Dec 11 20:15:17 grendel /kernel: pid 10062 (named), uid 53:
exited on signal 6


Now I know the problem in the config was that I wrote one
instead of two /'s, but those stale errors look
strange....any ideas what they mean?

Thank you,
Thomas
