articles appearing in wrong newsgroups

[Edwin]

Hello,

I'm using INN2.2 and CNFS buffering on a Solaris 2.6 O/S.  I'm having a
very strange problem.  Some articles being posted into one local
newsgroup are also appearing in another local newsgroup under a
different subject heading (effectively replacing the original article
there).  Does anyone know why this might be happening?  It doesn't seem
to matter if the articles are being cross-posted or not.  The same thing
occasionally happens.  We have a 0.5Gb CNFS buffer set up for these set
of groups and I know we can't have filled that up so quickly.  There
aren't enough articles to even fill up 100Mb as of yet.

Any ideas?
