背景描述：
最近一个项目的系统管理员和业务运维人员分别反馈问题：
1、应用系统每个月会有一两次宕机，需要管理员手工重启IIS；
2、财务模块一个功能经常报网络错误“网络异常，请检查网络连接”“Unable to read data from the transport connection: 远程主机强迫关闭了一个现有的连接。”
财务组开发人员联系到我，他按照常规排除法，测试反馈：在应用服务器访问本机也会出现上面提到的网络问题。
异常信息（异常类型：System.Net.WebException）
异常提示:网络异常，请检查网络连接

问题分析：
貌似跟网络没有关系？？要来应用系统的服务器日志。从“系统”日志中看到连续5次进程崩溃的警告信息后，紧接着AppPool就自动禁用了。
应用程序池“ASP.NET v4.0 cwbaseAppPool”将被自动禁用，原因是为此应用程序池提供服务的进程中出现一系列错误。
为应用程序池“ASP.NET v4.0 cwbaseAppPool”提供服务的进程在与 Windows Process Activation Service 通信时出现严重错误。该进程 ID 为“27048”。数据字段包含错误号。
W3WP进程为什么会崩溃呢？查看对应的“应用程序”日志：*Exception
