IIS应用程序池回收触发器：没有足够的存储空间来完成此操作（Azure App Service）

Question

我正在Azure应用服务上运行ASP.Net网站，每次发生应用程序池回收时，该服务都会挂起。

我已经检查了可用的存储空间，我正在使用50 Gb中的大约5 Gb，这应该不是问题。

请参阅下面的堆栈跟踪。有人有主意吗？我已经向Microsoft支持部门询问了此问题，他们无法回答这一问题：-（

最坏的情况下，我可以阻止System.Diagnostics.Eventing.EventProvider.EtwRegister()通话吗？

非常感谢您提供帮助！

最后，问题确实出在句柄计数太大而无法为IIS处理。调查指出，Imagprocessor（http://imageprocessor.org）的文件缓存实现导致了此问题。

• 您可以在Azure门户的“指标”部分查看有多少人处理您的App Service
• 您可以在https://[your-app-service].scm.azurewebsites.net中找到详细信息。转到进程资源管理器->选择w3wp.exe的属性->选择“句柄”选项卡
