IIS Apppool删除与WCF服务的连接

时间：2018-06-13 16:22:49

标签： c# wcf iis logging application-pool

我遇到一个应用程序池超时一次请求它总是超时大约5分钟。我已启用跟踪，但未记录Warning，Error，Critical个事件。 EventViewer中也没有任何活动。我启用FailedReqLogging并将其设置为在4分30秒内记录任何请求。我在C:\inetpub\logs\FailedReqLogFiles\W3SVC2目录中找到了以下内容：

Logs

我更改了哪些IIS设置以容纳此请求？ Failure Reason它列为TIME_TAKEN所以我猜测AppPool超出了一些时间限制。这个限制是什么？

我还注意到Final Status列在200。这意味着我在Warning，Critical或Fatal的日志中看不到任何内容，因为它记录为OK。我是否正确的假设？

以下是客户端跟踪日志中的异常堆栈跟踪。请注意，服务器跟踪日志中未显示任何错误。奇怪的是，内部存在多个嵌套异常，但没有一个具有实际价值。

此服务适用于其他客户端。只有这个客户在5分钟内遇到问题。不同Web服务器上的其他客户端完成请求。

1 个答案:

答案 0 :(得分：1)

五分钟限制听起来不像default timeouts

中的任何一个

所以我看了一下应用程序池的高级设置，并查找了默认为5分钟的设置，看起来可能有问题。我发现你可能会尝试一对。您可能想采用这种方法：

  1. 在IIS管理器中，转到“应用程序池”
  2. 找到您的应用程序池，右键单击，选择“高级设置”
  3. 扫描设置列表并查找5分钟设置并尝试通过增加值进行选择性调整（强烈建议阅读并了解每个设置的内容）

    4. 向我跳出的几个5分钟设置是 CPU 下的限制间隔（分钟）和快速失败保护下的故障间隔（分钟）。

    不能保证这样，但除非你手动将默认值设置为5分钟，否则这是一个合理的地方，可以开始寻找5分钟的设置。一次更改一个设置，重新启动应用程序池并进行测试。请注意，如果您的代码中存在类似无限循环的问题，显然没有超时值可以帮助:-( 祝你好运。
