Urgent help needed with SORBS

[Michael Tokarev <mjt () tls msk ru>]

This may be somewhat off-topic here, but still..

Today at about 00:00 UTC, one of SORBS official
nameservers somehow got a corrupt datafile, and
started spreading incorrect information.  The
problem had gone at next reload or next data
transfer (which was after about 20 minutes),
but some caches got corrupt data.  We need to
identify the "bad" nameserver, but so far was
unable to do so.

If you're running BIND8 caches (note bind8,
bind9 won't not help), and are expiriencing
problems resolving dnsbl.sorbs.net zone, please,
perform a nameserver dump (by sending SIGINT
to the named process) and find the origin of
NS records for dnsbl.sorbs.net.

Problematic data is like this:

dnsbl.sorbs.NET.        119671  NS      \@.
                        119671  NS      safe.
                        119671  NS      socks.
                        119671  NS      ip4set.
                        119671  NS      relays.
                        119671  NS      proxies.
                        119671  NS      sDATASET.

(as of why this happened, -- that's another
topic, I have only one guess - two processes
writing into the same file at the same time,
which may, in theory, have this effect, -- but
in order to be able to check this, we need to
determine which nameserver performed badly).

Thank you.
