The only thing I can guess at is that xrange plays funnily with Zope in this case. For some reason the list items generated by xrange() might not be released for garbage colletcion. If so it is probably a bug. Try: class testProd(SimpleItem.SimpleItem): """ testProd docu """ meta_type = 'testProd' def __init__(self, id, title = ''): self.id = id self.title = title self._tree = [] for i in range(200): n = item(str(i),i) self._tree.append(n) On another note. Why do you do all the : tree = self._tree tree.append(n) self._tree = tree isn't: self._tree.append(n) Just as good, and 2 lines shorter? regards Max M
