Dear Managers,
My original problem was:
> sometimes named daemon dies (first time was 2 weeks ago and now) and I
> cannot find out why.
> We are running DU 4.0b on DEC 3000/300.
> After (re)starting named, sendmail (8.9.0.beta5) and listprocessor
> (6.0c) are confused, I have to stop them and delete all queued mail.

Ian Mortimer pointed out that follows:
This could be due to the DNS security bug which affects versions of
BIND prior to 4.9.7 which means the one shipped with DU 4.0b.
If that's so then someone is attempting to exploit this vulnerability
to break into your system. The good news is that DU's version of
named just dies and dumps core so they won't succeed in breaking
in that way.
The solution is to upgrade to either BIND 4.9.7 or BIND 8.1.2.
The first is the easiest quick fix because it's compatible with
the version shipped with DU (4.9.3).
You can get BIND from
http://www.isc.org/bind.html
Your sendmail problems most likely result from the nameserver
crash.
