I'm wondering if anyone has come across this particukar problem:

error: client 10.0.1.114#24522: updating zone '10.IN-ADDR.ARPA/IN' : Novell DDNS : Failure in write_to_journal_and_edir. Add failed for reverse zone
error: client 10.0.1.114#24539: updating zone '10.IN-ADDR.ARPA/IN' : Novell DDNS : Failure in write_to_journal_and_edir. Add failed for reverse zone
error: client 10.0.1.114#24553: updating zone '10.IN-ADDR.ARPA/IN' : Novell DDNS : Failure in write_to_journal_and_edir. Add failed for reverse zone
Etc, etc, etc...

I have trawled the internet to no avail.

Thanks in advance.
