I've checked my logs for conflict errors with session machinery. I also had times earlier than zope startup:
http://mail.zope.org/pipermail/zope-dev/2007-April/029244.html I don't know why... Maybe your problem is simply that 'create_level' does something with Catalog (as Tres Seaver suggested). If so, then if one transaction changes it then second transaction raises conflict. With sessions I had problems with OOBTree not IOBTree. -- Maciej Wisniowski _______________________________________________ Zope-Dev maillist - [email protected] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
