Lookup failures

[Ondřej Surý]

Hi Steven,

sorry to hear that.

Does this happen only with this specific domain or it happens with different names too?

If you can reliably reproduce the problem, you can either bump up the debugging (-d 9 argument to named) or capture the traces.

Are there any other log entries preceding the snippet you posted?
