I'm trying to put together a collaboration app that allows users to share large datasets. When I ftp the data, which has numerous folders and large (~100Meg) and small files in them, to a Zope 2.6.0 server running on Windows XP, it will transfer many but not all of the datasets. Then if I try to make another object, say a folder, through ftp or the management screens, the server hangs. The same test on a Linux box running Mandrake 8.something doesn't show this problem at all. Ideas? I would guess that it's a threading problem, mostly because in my experience threads suck on Windows, but I don't know enough about the Zope internals to prove it. Changing the backend from FileStorage to DirectoryStorage(lawn) didn't seem to change the behavior either. Any help, yada yada... J. Toman
