Thank you for your advice; I did as you suggested and now inndf
reports "48 % overview space used" and "1387329 overview data stored"
which gives 1.03 as the crossposting ratio.

I have also changed the line

!!! ${INNDF} ${OVERVIEWDIR} ! lt ! ${INNWATCHSPOOLSPACE} ! throttle ! No space (overview)

in innwatch.ctl to

!!! ${INNDF} -o ! gt ! 85 ! throttle ! No space (overview)

which I hope will give some warning...

Do people think that the build up of article records is due to
expireover failing before it finished and leaving both the new records
(with the expired articles removed) and the old records in the buffer?

Or has there been a significant change to the buffindexed code since
inn-2000-02-07_03-02?
