Hello, I am getting a fair number of these errors popping up: Error Type: AssertionError Error Value: newInteraction called while another interaction is active. I searched for the error mesage and only came up with a reference to Philipp von Weitershausen's book, which I have, but it really doesn't tell me much (while it quite possibly would tell another plenty :). Strangely, the logs do not show this error, but they do have Unauthorized Errors correspondding to the page template that was being requested when the newInteraction error was thrown. Our environment looks like this: Zope Version (Zope 2.10.6-final, python 2.4.4, linux2) Python Version 2.4.4 (#2, Mar 7 2008, 03:56:06) [GCC 4.1.2 (Ubuntu 4.1.2-0ubuntu4)] System Platform linux2 SOFTWARE_HOME /opt/testsite.com/parts/zope2/lib/python ZOPE_HOME /opt/testsite.com/parts/zope2 INSTANCE_HOME /opt/testsite.com/parts/zclient1 CLIENT_HOME /opt/testsite.com/var/zclient1 Network Services ZServer.HTTPServer.zhttp_server (Port: 8050) Process Id 1024 (-1247577200) Running For 1 day 6 hours 12 min 1 sec Any advice greatly appreciated.
