In windows, i'm unable to use the same port after server has started

[Chris J. Lee]

Problem

In windows, i'm unable to use the same port after server has started. It says it's being in use:

Microsoft Windows [Version 6.1.7601]
Copyright (c) 2009 Microsoft Corporation.  All rights reserved.

C:\cygwin64\home\chris\workspace\hexo-zf>hexo server --port=4001
hexo server --port=4001
FATAL Port 4001 has been used. Try other port instead.
FATAL Something's wrong. Maybe you can find the solution here: http://hexo.io/docs/troubleshooting.html
Error: listen EADDRINUSE
    at errnoException (net.js:901:11)
    at Server._listen2 (net.js:1039:14)
    at listen (net.js:1061:10)
    at net.js:1135:9
    at dns.js:72:18
    at process._tickCallback (node.js:415:13)

I don't have any other instances of the server running. I double checked as well.

Steps to reproduce

1. Start the server hexo server
2. Stop the server
3. Try to start it again with the same port

This is the expected behavior of TCP/IP network, only one process can bind to a port.
It seems you have another process using 4001, try other port instead.
