需要帮助调试服务器崩溃的原因。 Win 2008 上的 IIS 服务器，CPU 负载正常，内存使用日志，似乎没有任何问题。
w3p 进程随机崩溃。在事件日志中我首先看到:
Faulting application name: w3wp.exe, version: 7.5.7601.17514, time stamp: 0x4ce7afa2
Faulting module name: System.Runtime.Serialization.ni.dll, version: 4.0.30319.18044, time stamp: 0x51271348

Report Id: 5beef11c-1b0c-11e3-8eec-0026b9347fe0
然后我看到:

然后:
Faulting application name: w3wp.exe, version: 7.5.7601.17514, time stamp: 0x4ce7afa2
Faulting module name: clr.dll, version: 4.0.30319.18052, time stamp: 0x5173c114

Report Id: 7e58b5f2-1b0c-11e3-8eec-0026b9347fe0
之后应用程序池进入停止状态。
所有网络服务异常都已处理，我不知道去哪里查找。系统可以稳定很长一段时间(几天)，然后随机崩溃。
有什么方法可以找到此类问题的根本原因吗？
如果 IIS 内部发生此类崩溃，是否有任何方法可以监视服务并重新启动？
编辑:
了解更多详情。调试诊断工具能够读取内存转储。似乎是 WCF 调用导致的。看起来当我创建 WCF 服务实例并开始反序列化消息时，它会进入无限循环。关于如何获得有关正在发生的事情的更多详细信息有什么想法吗？在此堆栈中我看不到任何代码。我把中间部分剪掉了，它只是在序列化DLL中重复调用

最佳答案
事件日志中的详细信息确实指出了序列化问题，但我不记得导致 w3wp 崩溃的序列化问题。 首先，打开 WCF 跟踪以获取 WCF 日志并查看确切的序列化问题(如果是这种情况)。 http://msdn.microsoft.com/en-us/library/ms733025.aspx
其次，关于故障转移，如果应用程序池崩溃，它将自动重新启动。但是，如果重新启动后池再次崩溃，在给定时间段内多次崩溃(默认情况下 5 分钟内崩溃 5 次)，应用程序池将被停止以防止更多崩溃 - 这应该在事件日志中显示。
至于序列化问题——如果你无法从trace中找出问题所在，你可以在这里发布xml内容吗？或者将其上传到某处并提供链接？如果您使用 HTTP 绑定(bind)，您只需打开 Fiddler 并复制请求内容即可。如果您使用 TCP 或其他绑定(bind)，则可以使用 WCF 消息日志记录来记录消息(不要忘记将 LogEntireMessage 设置为 true)。 http://msdn.microsoft.com/en-us/library/ms730064.aspx
关于wcf - WCF 的 IIS 进程随机崩溃，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/18749263/
