Hi there, I think I've seen an earlier report and I'd like to confirm this. XML Document appears to leak memory pretty badly: * When rendering it with DTML to HTML, Zope's memory use often goes up a few kilobytes. Not all the time, it appears, but a reload often does the trick. * It also appears that doing a DOM manipulation (for instance appendChild) increases Zope's memory use significantly; by a few 10s of k. Now, I'm using some external methods to render and manipulate this document, so I may be introducing some circular references there instead. I'll try to find a simple test case. Zope's memory use is easily driven up by a couple of megabytes in a short time by what I'm doing, which is rather annoying. Anyone has any idea on what may be going on? Regards, Martijn
