stream.pipe(request) Error: socket hang up

Hi:
I have a problem，
code:
```
var stream = fs.createWriteStream(path.join(__dirname, './test.json'));
request = new Request(method, url);
stream.pipe(request);
```
Upload about 100 K file no problem
But there will be a mistake in more than 200 K

Error is
```
{ Error: socket hang up
at createHangUpError (_http_client.js:254:15)
at Socket.socketCloseListener (_http_client.js:286:23)
at emitOne (events.js:101:20)
at Socket.emit (events.js:188:7)
at TCP._handle.close [as _onclose] (net.js:498:12) code: 'ECONNRESET', response: undefined }
```
After the examination, no problems were found, can you help me?
