[Zope-dev] Zope 2.7 memory behaviour

Hello, I´m trying to find a memory leak in a zope appliction and started to test how zope memory consume behaves basically under load. The current result is: Zope constantly consumes more memory. The testcase is: 12 http clients request constantly request the same page template (it does not contain any tal statements and only 10 lines of HTML) in a simple folder. The increase is about 50 - 100 kb / minute. I´m using Windows 2000 as server platform. The database cache and debug information on the control panel seem allright. Now I wonder if there´s basically a problem with Zope 2.7? Has anyone made the same experience? Or an explanation why this happens? Thanks, Arndt.
