I've put together a document describing most of our recent stability issues, and their solutions, up on http://www.zope.org/Members/matt/StabilityHOWTO Included in the document is a number of tips for trying to tweak zope if you are having problems to narrow down a probable cause. Note that to the best of our knowledge, Zope 2.5.1 and Zope 2.4.4 (both beta releases) in conjunction with Python 2.1.2 solve all known *Zope* problems. However, other products may have their own issues; part of the job of this HOWTO is to provide some degree of guidelines for how to report a problem to Zope, such that Zope Corporation and the Zope community can perform diagnosis and produce a remedy. -- Matt Kromer Zope Corporation http://www.zope.com/
