[Pan-users] "missing" articles

[Alberto BARSELLA]

Hello,
        I've experienced a strange problem (v 0.13.3), which may be due to pan,
my newsserver or my misunderstanding of NNTP.
I'm not able to reproduce it (and I also noticed it by chance). Basically, I was
donwloading a series of fansubbed episodes from one of the anime newsgroups
and I noticed the following for one of them:
- say that it was split in 10 rar files
- 5 rars were ok (all segments present -- pan's "green puzzle" icon)
- 1 was partial (only some segments -- pan's "red puzzle" icon)
- 4 were missing completely.

This is perfectly normal when the articles have not entirely propagated
to a newsserver: usually it's enough to look one day later and everything is
there.  Still, for this episode even after 2-3 days the situation was exactly
the same.

Now, if instead of opening the group and downloading new headers, I force a
reload of all headers (using "more download options...").  The "missing"
articles appear (and they appear marked as "read").
Could this be a problem with article counting?  My knowledge of NNTP is low, and
I don't know exactly how wraparound in article counting is handled in
large-volume newsgroups.

Is this a known issue?  (I searched the list archives for "missing articles" but
found none of the sort).

Bye,
Alberto
