Overview data goes wrong in inn-STABLE-20000825.

[tyro01]

Overview data goes wrong in inn-STABLE-20000825.
Is this my fault of configuring  or INN bug ?

The problems are ...
One Message-ID has two article number in a same group.
And Lines: of overview is not same as ther Line: head of 
the article.

I telnet to INN server and got following data.

I remade the buffinded buffer and makehistory -O -x -F, but could not
repair it. I tried overchan, but got same results.

My config files .. 
## inn.conf
ovmethod:               buffindexed
enableoverview:         true
useoverchan:            false

## buffinded.conf
0:/var/lib/inn/spool/overview/OV1:40280
1:/var/lib/inn/spool/overview/OV2:40280
2:/var/lib/inn/spool/overview/OV3:40280
3:/var/lib/inn/spool/overview/OV4:40280

How do I repair overview data  or debug it ?
I am sorry for my poor english.

TIA.
