Yike whats this [Undownloaded article 9563] 180 of them

[Harry Putnam <reader@newsguy.com>]

I just saw something I never saw before in my comp.lang.perl.moderated
group. This group is under agent control, and I just cvs'ed yesterday.

I happened to open it with a C-u <RET> and I found 189 messages that
say:
[...]
 1@  31-Dec [   0: Gnus Agent          ] [Undownloaded article 9561]
 1@  31-Dec [   0: Gnus Agent          ] [Undownloaded article 9562]
 1@  31-Dec [   0: Gnus Agent          ] [Undownloaded article 9563]
[...]

Note the old date.  And I've never seen this notation in a summary
buffer before. Gnus Agent listing out undownloaded articles like that.

The very odd thing is that this group was begun fresh Jan 9 and has a
predicate of `true'.  There should be no undownloaded articles.
Further these file numbers do not in fact exist.  Also, they are not
known to the .overview file, ditto .agentview.  Nor do they exit in
.newsrc.eld.  Agent.lib/history doesn't know about them either.

However I did find a huge list in agent.lib/history about a different
group that looks like:

[...]
No-Message-ID-in-article	730859	alt.solaris.x86 59576 
No-Message-ID-in-article	730859	alt.solaris.x86 59577 
No-Message-ID-in-article	730859	alt.solaris.x86 59578 
[...]

Why are article numbers differernt than file names there? And is it
likely there really weren't message ids in hundreds of messages.

Far as I know, my server hasn't undergone any major changes.

Anyone know what is happening here?
