Please provide more information.  Error message?  Which author?
Message-IDs of "duplicate messages"?  BTW, I don't understand what you
mean with the term "duplicate" or "identical" message.  In Usenet,
articles cannot be identical because at least the Message-IDs need to
be unique, else the news server would refuse to accept the second
message.

Could be a problem when sorting by date.  I can't reproduce the
problem when entering alt.os.linux.slackware (with ~1000) articles and
`gnus-thread-sort-functions' set to '(gnus-thread-sort-by-date).
(Using Emacs 22.)

I can't find/recall such a report.  Cc-ing ding.

If Gnus fails in XEmacs, this is most probably irrelevant to
emacs-devel.

This package is a old CVS snapshot from the stable branch of Gnus.
Isn't there a Gnus 5.10.8 XEmacs package available?

Bye, Reiner.
