This is a known issue with the sessioning machinery in Zope 2.5.X. I'd suggest upgrading to 2.6.0... Thanks, - C On Tue, 2002-10-29 at 08:49, Kevin Carlson wrote:

I am getting an intermittent error from the session_data_manager object that gives me the following information:

Error Type: KeyError Error Value: duplicate key 24438444A0h9Emyt1QA

The traceback is below. I have a Python Script named standard_security_header that is checking session data upon entry into certain pages. The line in that script that is referenced in the traceback is:

session = request.SESSION

Any idea as to why this duplicate key error is happening?

Thanks,

Kevin
