Hi Doug,
thanks for the valuable info. After a lot of debugging I reached to
the point where I get:
Jan 9 17:21:22 hp named[39053]:
/usr/src/lib/bind/dns/../../../contrib/bind9/lib/dns/journal.c:171:
unexpected error:
Jan 9 17:21:22 hp named[39053]: missing SOA
Some googling showed that this is a rather common error-bug with
DNSSEC. I am no expert here, so I will turn this to the bind mailing
list.
Regards
