[Zope] newInteraction error

[Erik Myllymaki]

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)]

Any advice greatly appreciated.
