WinSCP Network error: Software caused connection abort
WinSCP Network error: Software caused connection abort
我有一个预定的工作，每天通过 WinSCP 执行安全文件传输。该流程以 2 个 ssrs 文件共享订阅开始，这会在本地目录中删除 2 个文件。然后我安排的 sql 服务器代理作业启动一个 powershell 脚本，该脚本启动 winscp sftp 将 2 个文件传输到远程 SFTP 服务器。
工作和文件传输在 2 个月内都工作正常，直到上周随机出现工作在某些天（但不是其他天）开始失败。日志显示一个神秘的网络错误 "Software caused connection abort"。我在这里查看了 winscp 的支持文档 https://winscp.net/eng/docs/message_software_caused_connection_abort, here https://winscp.net/eng/docs/message_unexpected_close here https://winscp.net/eng/docs/faq_connection_refused and other sources here https://www.hostingride.in/content/solved-network-error-software-caused-connection-abort-winscp-error-putty-keepalives
根据我找到的建议：
a) 向 windows 防火墙添加了例外以允许 winscp 通过。
b) 在 WinSCP 高级站点设置中的 Keepalives 下启用 "Executing dummy protocol commands"
c) 将服务器响应超时和保持活动之间的秒数增加到每个 360 秒
None 解决了这个问题。奇怪的是，文件传输并不是每天都失败。 运行 作业反复（相同的代码）通常失败但偶尔会成功（见附件的 powershell 屏幕截图）
如果有人熟悉如何解决此问题，请告诉我。请参阅随附的日志条目和 powershell 屏幕截图。
