Session conflict errors are very common -- for the following reason: While individual sessions are usually used only by a single request at a time, they share common administrative data structures (e.g. the OOBTree that holds the session objects). The administrative data structures usually have conflict resolution *BUT* conflict resolution requires sufficient history -- and the temporary storage usually holding the sessions only has minimal history. Therefore, conflict resolution is usually ineffective (impossible) and you get lots of conflicts. -- Dieter _______________________________________________ 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 )
