asmx 服务突然停止工作并在系统重新启动后正常工作

Question

我创建了一个 web 服务，它在应用程序登录时对用户进行身份验证。 它自 7 年以来一直运行良好，但现在它突然停止工作，但是当我们重新启动应用程序服务器（部署我们的应用程序）时，服务开始工作。 我们已尝试但未能诊断出问题。

我们有两台服务器，一台用于部署服务，另一台用于应用程序。 应用程序是 windows 应用程序，它是通过远程桌面 web 服务器访问的。

我们所做的：

1. 检查了事件，但没有收到任何错误。
2. 更改了 asmx 服务的端口
3. 禁用防火墙
4. 在不同的服务器上部署服务

以下是错误：
