Hi, For some tests I have done : - Create about 5000 folders under the Root Zope Site - Inside those folders, I have created about 30 000 objects ( as document, just an id, title and a Type). - I've catalogued all inside a catalog named TheCatalog I have written just this function, in intend to test my CPU ( that why I've written it like this): allobject = context.TheCatalog.searchResults(Type='TypeTest') l=len(allobject) i = 0 #for i in range(len(allobject)): for object in allobject: #path = allobject[i].getPath() #course = allobject[i][0] path = allobject.getPath() course = allobject[0] thepath = string.split(path,'/') lepath = string.join(thepath[:-1],'/') lieu=context.restrictedTraverse(lepath) lieu.manage_delObjects(course) i+=1 return "Len: %s and Number parsed: %s" %(i,l) Phase A: I have 30 000 objects and the message following: Len: 30000 and Number parsed: 15001 In my catalog: 15000 object only were destroyed. !!! Phase 2: I de-comment my comment lines, but I've got the same message. I try to understand what it happens, but I can't. Anyone has a brillant idea?
