it is a bit disconcerting to realise that a couple of the repeated messages are
your own, and know that it is a while since they were sent. Just a possible
pointer - it seemed to me that the repeated messages referred to topics where
somebody posted a new message - is the archiving software getting screwed up
when trying to add a message to a thread causing it to repeat old messages?
this may be an invalid pointer as I have not done a proper investigation along
this line, but it was an impression I got that is possibly worth investigating.
