The "Connection reset by peer" message means that S3 broke the connection on their end. This is usually a momentary error, their server is too busy perhaps. There isn't anything that we can do on our end to prevent it.
The column message is a new warning. Nicholas gave me this information for another ticket:
As long as their target server has a high enough MySQL maximum packet size they can ignore this warning. If they get restoration errors they should read this warning again and set the max packet size higher because that's a MySQL limitation.
Also in general large columns are not a brilliant idea anyway
