场景

WCF应用程序部署在IIS7中，使用net.tcp协议对外给几百台客户端提供服务，应用程序池不断崩溃重启。

分析过程

  • 在事件查看器中看到的错误信息类似于

为应用程序池“XX”提供服务的进程在与 Windows Process Activation Service 通信时出现严重错误

  • 使用windbg在崩溃时进行分析，找到引发崩溃的堆栈的最顶部信息进行搜索，找到两个补丁包安装上

用于搜索的顶部异常信息为：IOCompletionThunk.UnhandledExceptionFrame BeginReadCore

:> !analyze -v

结论

使用以上方式依然未解决问题。

不过之后使用同事的机器重新编译部署了后运行了两天竟然妥妥的，所以我猜可能是OS或VS的问题。

之后继续观察。
