Thanks for the report. Would it be possible for you to follow the instructions at https://wiki.mozilla.org/CloudServices/Sync/File_a_desktop_bug and attach some Sync logs?

Thanks - but that log appears to have been truncated. I'm expecting to find an error referencing NS_ERROR_NET_PARTIAL_TRANSFER near the end of the logs.

Thanks! The logs show this is a duplicate of bug 1294270. We should have a short-term fix for this rolling out to production soon via bug 1294595.
