CYGWIN SFTP不能突然工作。 authentication后closures连接

我几周前在一些Win 2003 R2 x64服​​务器上安装了用于SFTP的CYGWIN，最初所有的工作都没有问题。 然而，本周的问题上升，用户无法将SFTP到2个服务器。 连接时，authentication后立即出现错误“连接closures”提示。 对于第一台服务器，我们重新安装并重新configurationCYGWIN，并重新开始工作。 但是，今天另一台服务器再次击中相同的错误，所以我想找出什么是错误的，以防止其他服务器遇到同样的问题。 我做了一个SFTP -v，输出如下： 

OpenSSH_6.7p1, OpenSSL 1.0.1k 8 Jan 2015 debug1: Reading configuration data /etc/ssh_config debug2: ssh_connect: needpriv 0 debug1: Connecting to 192.168.1.1 [192.168.1.1] port 22. --truncated due to characters limitation-- debug1: Next authentication method: password [email protected]'s password: debug2: we sent a password packet, wait for reply debug1: Authentication succeeded (password).

（我比较debugging信息与SFTP仍在工作的服务器，从这里不同的开始..）

– 由于字符限制而被删除 –

谷歌search，看到/ etc / passwd的一些提到的问题，但我再次尝试mkpasswd，它不工作。
任何帮助将不胜感激。

这里是syslog ng，但似乎无法find有用的信息在这里。

它表示收到与客户端的断开连接，但在客户端，连接在authentication后立即closures。
谢谢。

再次编辑，添加DEBUG3日志级别。
