We don't actually try to build the XML which may be the issue. We just take the stream from Flash and write to the disk. Either Flash is sending truncated data (and the wrong size to match) or it is being truncated when received by save.php...

What I've seen is that the PHP (or whatever) can't read the XML file as it has the wrong encoding specified, or it just somehow contains characters that are invalid.

see e.g.
