SocketException: Write failed (OS Error: The operation completed successfully.

Dart Experts,

Do you have idea what this Exception really means.

Unhandled exception:
SocketException: Write failed (OS Error: The operation completed
successfully.

, errno = 0)
#0 _DefaultZone.handleUncaughtError.<anonymous closure>
(dart:async/zone.dart:148:7)
#1 _asyncRunCallback._asyncRunCallback
(dart:async/event_loop.dart:9:15)
#2 _asyncRunCallback._asyncRunCallback
(dart:async/event_loop.dart:13:7)
#3 _createTimer.<anonymous closure>
(dart:async-patch/timer_patch.dart:8:13)
#4 _Timer._createTimerHandler._handleTimeout (timer_impl.dart:91:28)
#5 _Timer._createTimerHandler._handleTimeout (timer_impl.dart:99:7)
#6 _Timer._createTimerHandler.<anonymous closure>
(timer_impl.dart:107:23)
#7 _ReceivePortImpl._handleMessage
(dart:isolate-patch/isolate_patch.dart:81:92)

It sometimes(not always) happens when I do Socket.add(). The message of the
exception is kind of "inconsistent" because it says

"The operation completed successfully.

, errno = 0)"

My program runs on Dart VM(Dart SDK version 0.5.20.4_r24275); Win7 64
bits. Any insider knows what this exception really is about?
