Hi John, I tested Multipart Upload with aws-sdk-js with the patch you mentioned, against riak_cs (s2), upload finished without errors up to 1GB object. The environment is all local on my laptop, so latency is small. The script I used is in [1].
As Luke mentioned, HAProxy would be the point to be investigated first. Or, if it's possible to get packet capture, by finding some wrong TCP packet, like RST or premature (from the point of HTTP) FIN, one can identify who closes TCP connection actively. In this case, packet should be captured on client box, HAProxy box and riak cs box.
