I think this is not a bug. A 600MB file would be expected to fill the SWAP space, and therefore fail. A consistent case with a 40MB file that does not fill up any swap space or virtual memory could be a bug, but more info is needed.

I believe I have experienced the same problem but with a smaller file (only 40MB) running on Windows 2k

This looks like a memory problem. In general Zope stores
uploaded content in a temporary file before it stores
the data inside the ZODB. 

Beside the reported problem, do really want to store
such big pieces of data inside the ZODB? Better you 
use Apache to serve such large pieces of data instead
using the ZODB.

I am trying to build a Software Archive using Zopes
built-in FTP-Support. When I try to upload a large file (600MB+) I get the following behaviour:
Windows:
After a while the zope server raises an uncaught out of memory exception:
<snip>
2002-06-11T23:07:39 ERROR(200) ZServer uncaptured python exception, closing chan
nel <ZServer.medusa.ftp_server.recv_channel connected at 0x16e1c7c> (exceptions.
MemoryError:out of memory [R:\KORNSP~1\ZServer\medusa\asyncore.py|poll|94] [R:\K

edusa\ftp_server.py|handle_read|937] [R:\KORNSP~1\ZServer\FTPServer.py|write|538
])
</snip>
and my client (Internet Explorer 6.0) crashes

Linux:
Pretty much the same. As I upload the file I can watch my swap partition fill up. I didn't have the guts to see it through to the end, though ;-)

WebDAV(using windows built-in WebFolders) doesn't work to well with large files either, though I couldn't collect any information on that problem till now.
