[Zope-dev] Zope 2.1.6 Memory issue

[Shane Hathaway]

Jason,

Try /Control_Panel/manage_debug ... it will tell you exactly which
kinds of objects are eating memory.  Take a "snapshot" then refresh the
page after a couple of minutes, and the table should list at the top
the name of the class that's taking up more than its fair share.
