任何关于这一想法的帮助都是有益的。

在Azure中运行的.NET Core 3.1.0 Web API应用程序中，我有一个应用程序在写入EventLogger时遇到了相同的问题。我们正在使用内置ILogger和NLog来保存日志，以Stackify和Raygun

我们的应用程序使用了MediatR库，我们用额外的日志记录对管道执行进行了包装，这样每次执行不同的命令时，我们都会记录所花的时间。我们的应用程序广泛使用日志记录。这些问题大多发生在用户活动显著增加时

这些错误将以AggregateException的形式显示在日志中：

写入记录器时出错。（该进程无法访问该文件，因为另一进程正在使用该文件。）

除了内部例外：

System.Diagnostics.EventLoginInternal.InternalWriteEvent（UInt32事件ID，UInt16类别，EventLogEntryType类型，字符串[]字符串，字节[]原始数据，字符串currentMachineName）
System.Diagnostics.EventLoginInternal.WriteEvent（EventInstance实例，字节[]数据，对象[]值）：170
Microsoft.Extensions.Logging.EventLog.WindowsEventLog.WriteEntry（字符串消息，EventLogEntryType类型，Int32 eventID，Int16类别）：129
Microsoft.Extensions.Logging.EventLogger.WriteMessage（字符串消息，EventLogEntryType EventLogEntryType，Int32 eventId）：158
Microsoft.Extensions.Logging.EventLogger.Log[TState]（日志级别LogLevel，EventId EventId，TState状态，异常，Func3格式化程序）
Microsoft.Extensions.Logging.Logger.g|u LoggerLog | 12_0[TState]（LogLevel LogLevel，EventId EventId，ILogger Logger，异常异常，Func3格式化程序，列表1和异常，TState和状态）：45

我们基本上会看到数百个这样的错误，这将导致我们的应用程序变得无响应和超时请求。但是--我们的应用程序不需要EventSource日志记录，因此我们采纳了@Dan Kroymann的建议，从Progam.cs中配置的日志记录提供程序中删除了EventLog，例如

public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
            .ConfigureLogging((hostingContext, logging) =>
            {
                logging.ClearProviders();
                logging.AddConfiguration(hostingContext.Configuration.GetSection("Logging"));
                logging.AddDebug();
                logging.AddConsole();
            })
            .ConfigureWebHostDefaults(webBuilder => webBuilder
                .UseStartup<Startup>()
                .UseNLog());

公共静态IHostBuilder CreateHostBuilder（字符串[]args）=>
Host.CreateDefaultBuilder（args）
.ConfigureLogging（（hostingContext，logging）=>
{
logging.ClearProviders（）；
logging.AddConfiguration（hostingContext.Configuration.GetSection（“logging”））；
logging.AddDebug（）；
logging.AddConsole（）；
})
.ConfigureWebHostDefaults（webBuilder=>webBuilder
.UseStartup（）
.UseNLog（））；

为了使用某些日志扩展方法，您可能需要参考其他nuget软件包：

Microsoft.Extensions.Logging

Microsoft.Extensions.Logging.Console

Microsoft.Extensions.Logging.Debug

一旦我们安装了上述修复程序，我们就不再看到EventSource日志记录问题。

您是否尝试重新启动应用程序服务？你们看到这种情况一直发生吗？你们最终找到原因了吗？不，我仍然在应用程序中看到这些错误insight@BhargaviAnnadevara-MSFT我尝试重新启动应用程序服务，但没有帮助。@BhargaviAnnadevara MSFT我在我的许多应用程序服务中都看到了这一点。我的分析表明，当日志记录尝试大量出现时（例如，当SQL数据库之类的依赖项失败，导致大量请求抛出异常时），就会发生这种情况。一些错误日志记录调用最终会遇到此异常，这反过来会生成更多日志记录，从而进一步加剧问题。最近，为了避免这个问题，我开始从我的应用程序配置中删除事件日志记录提供程序。如果我们确实需要事件日志怎么办？@Dagrooms那么我可能建议创建一个静态ApplicationLogger，在启动时注册，并在整个应用程序中使用它。您需要确保资源（在本例中为EventLog）不被并发访问。
