socket.error during s3 upload

This seems to happen intermittently:

    boto_try(s3.meta.client.upload_file, Filename=os.path.join(LOG_DIR, self.out), Bucket=LOG_BUCKET, Key=self.out, ExtraArgs=AUTH_READ)
  File "processor.py", line 65, in boto_try
    return func(**kwargs)
  File "/usr/lib/python2.7/site-packages/boto3/s3/inject.py", line 106, in upload_file
    extra_args=ExtraArgs, callback=Callback)
  File "/usr/lib/python2.7/site-packages/boto3/s3/transfer.py", line 275, in upload_file
    future.result()
  File "/usr/lib/python2.7/site-packages/s3transfer/futures.py", line 73, in result
    return self._coordinator.result()
  File "/usr/lib/python2.7/site-packages/s3transfer/futures.py", line 233, in result
    raise self._exception
socket.error: [Errno 104] Connection reset by peer

I expect this to be caught by boto3 and raise a ClientError.

Note/aside: There’s a discrepancy between python 2 and 3 isinstance(socket.error, OSError) on python 3 but not python 2.
