我在其他论坛上进行了很多搜索，但无法找到根本原因.我还观察到另一件事-我尝试使用SFTP的文件名是* .xml，当我将其更改为* .XML时，SFTP是成功的".很奇怪，无法确定问题所在.我正在尝试使用JSch Java API.但是在尝试WinSCP前端时，我也遇到了同样的问题.

I have searched a lot on other forums but could not get to the root cause. I have observed one more thing - the file name, I am trying to SFTP, is *.xml when I change it to *.XML the SFTP is "successful". Very weird could not identify the issue. I am trying this using JSch Java API. But I have seen the same issue while trying the WinSCP front end.

您必须查看 SFTP服务器日志来查找更多信息.

尽管最常见的原因是缺少可用磁盘或用户配额空间-通常可以通过创建大小为零的文件来识别.

Though the most usual cause is a lack of free disk or user quota space – Which can usually be identified by the file being created with zero size.
