I found an interesting post about this [1]: apparently Diablo will forward a request by Message-Id to a different system, which likely has different article numbers. If load balancing is used this might explain why I get sometimes different article numbers. >> Is there any way to make Gnus fetch the whole article at once instead of >> first fetching the header and then the whole article?

If I post a followup to an article to a different group (e.g. a random *.test group) and then try to fetch the parent article it works without problems. The problem only occurs if the parent was posted in the same group as the followup and Gnus tries to guess the article number. If Gnus behaved as in the first case, everything would be fine.
