Look at your undo log.  If the conflicts don't correspond with entries 
in the undo log, and you're not mounting other databases, the conflicts 
are almost certainly due to sessions.  However, conflicts are a normal 
occurrence and rarely reach the user.  Zope automatically retries the 
request and delivers the successful page.
