The two interesting things that I see here is: - the multipart upload size for each part is on the big side (is it 1GB for each part?) - it seems that there are a lot of parts that suffered from retries, could be a source for the 512k issue > http://pastebin.com/5TnvgMrX --- python download code > > The weird part is every time I download the file it is of a different > size.

Usually that means that there was some error in the middle of the download, maybe client to radosgw communication issue.
