[Zope] ZODB conflict error AFTER adding an 'Access Rules'

Hi again,

Thank you for your explanation Dieter. Do you have any clue why I'm
having write conflicts when I add a call to the "change_skin" method in
the "Access Rule" of our Plone site !!! ??? Even when we just browse the
website, no update being made...

Is it possibly that it is a bug in CMF? In Zope? In the ZODB?

Regards,

-- Jean

What you see are write conflicts affecting oid 0x11 and 0x12,
respectively.

Read conflicts are reported as "database read conflict error".
Usually, Zope can tell you the oid and the class of the
affected object for read conflicts.
