 Status: Pending => Resolved

This is actually two separate bug reports.  The first bug report, a KeyError in sessioning, is fixed in CVS (what will be 2.7.1).  The second bug report "max transient objects exceeded" is not a bug; you need to set this higher in zope.conf (Zope 2.7.X).

Hm, 2.5.1 is a little old. Is there any chance You could
upgrade to 2.6.4 ?  Things have changes a little 
in between.

The non persistent behaviour if the
"Maximum number of subobjects" property is not a bug;
use the ZSESSION_OBJECT_LIMIT environment variable
instead for a more opersistent setting
(see docs/ENVIRONMENT.txt )

We just noticed also that when you restart Zope, then "Maximum number of subobjects" in /temp_folder/session_data is reset to 1000.

We set the limit of subobjects to 10.000, but we just got the message MaxTransientObjectsExceeded, and the website didn't work after this. This is not the error we are reporting. However, here is the traceback.

The error we are reporting, is that we can't go into temp_folder after the incident. We get KeyError. Here is the traceback:

You can simulate by setting the session limit to 1, and then visit the website from two different browsers.
