But because of my makehistory run this uniover info came from my
cycbuffs. And all articles with corrupt xover info have correct headers
in the cycbuffs.

Correct. As all n* newsgroups are in just one uniover file
(/news/uniover/13/overview) i just had a look at it and immediately
found errors in it (see below). But not all n* groups have xover errors,
fi, has > 1000 articles in it here and show no xover errors ...

Last two entries are clearly wrong. So probably my uniover problem is
limited to this file. If i'm correct this uniover format is removed in
2.3, so it is not very useful to create an 'uniover format checker'.
Also a makehistory run for just one uniover file would be handy, if not
for the removal of the uniover in 2.3 ... :-/

Note that most of this corrupt uniover file was generated by my
makehistory run. So simply running it again won't help. I think my
makehistory run is hindered by the same bug that caused the uniover
corruption in the first place.

Another thing that might be interesting; the xover estimate of the
number of articles in a group is way off. F.i.
211 10 930 970
has only 3 articles in it, not 10.

Any ideas ? I'm reluctant to upgrade to 2.3, although it might solve our
problem. Do you have an idea on how to find the real problem ? (our
number of user complaints is rising :(

And thanks to you all for your time of course ;)
