I've noticed a small number of duplicate articles on attcan in tor.news.* that
actually were processed as separate articles ...

It can't be explained by expire times, since we don't expire tor.*
for 7 days, and yet some of the articles arrived on the same day, or
a day apart. The usual check of the Message-ID showed that they
were identical.

I've never heard of this problem before ... and nobody has reported the problem
to me internally on any but the tor.news.* groups.

We're still running B-News 2.11.14 (although we'll move up to C-News when it
becomes available).

Here's a sample duplicate article from mark@sickkids:

	article headers (note identical Message-ID's):

		148:Path: attcan!utgpu!lsuc!sickkids!mark
		148:Message-ID: <259@sickkids.UUCP>

		151:Path: attcan!utzoo!yunexus!maccs!lsuc!sickkids!mark
		151:Message-ID: <259@sickkids.UUCP>

	history.d entries (note that they arrived the same day):

		<259@sickkids.UUCP>	04/22/89 02:23	tor.news/148
		<259@sickkids.UUCP>	04/22/89 13:02	tor.news/151

As we often get numerous duplicate articles because of our multiple feeds
(ie 1000-10000 per day :-) which are handled correctly, it seems odd that 
a few of the tor.news.* articles are slipping in past the B-News software.
 
Anyone have any clues?

Regards,
	Bob
