buffindexed overview has more articles than history

[Chris Martin]

A development server running inn-2000-02-07_03-02 has stopped because
the overview buffer is full.

The buffer is 1136 Mbytes in size and according to inndf -o -n has
2954450 overview data stored -- which I assume means article records.

However the history file has only 2792458 lines of which (grep '@'
history|wc) 1346662 are articles in the spool (almost all in
cycbuffs).

expireover runs but takes a suspiciously short time about it:

        expireover start Sun Feb 20 03:08:00 GMT 2000
        expireover end Sun Feb 20 03:08:05 GMT 2000

I can't follow the trail from expireover.c through ov.c to
buffindexed.c to be sure that it is using the right mathod 8(.

Can anybody suggest something to try next? I have no more space for
another buffer.

If it's of any help, here is the header from the overview buffer:

Index: 0, filename: /usr/local/news/spool/overview/OV1
 Buffer 0, len: 1136.10 Mbytes, (blocks) total: 145417,
        used: 145417 (100.0%), free: 145417
