The issue

I Made an update to my Windows Service and since then some testers random gets this error.
But its usually gone after i restart the service manually there. (but cant do it on hundreds of customers)

Note my Npgsql Version is 5.0.12.0 and not 5.0.10.0
I Also tried removing logging.AddEventLog(); from ConfigureLogging(last lines of error log indicates it)
but it still happened.

This is my Program.cs:

public class Program
{
    public static void Main(string[] args)
    {
        CreateWebHostBuilder(args).Build().Run();
    }

    public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>

            .UseStartup<Startup>()
            .UseApplicationInsights()
            .ConfigureLogging(logging =>
            {
                logging.ClearProviders();
                logging.SetMinimumLevel(LogLevel.Information);
                logging.AddEventSourceLogger();
                logging.AddEventLog();
            });
}

and appsettings:

{
  "Logging": {
    "LogLevel": {
      "Default": "Debug",
      "System": "Information",
      "Microsoft": "Information"
    }
  }
}

Any help with the idea when it happens or might happen would be beneficial.

I have an application that was experiencing the same issues writing to the EventLogger in our .NET Core 3.1.0 Web API application running in Azure. We are using the built in ILogger<> along with NLog to persist logs to Stackify and Raygun.

Our application used the MediatR library and we wrapped our pipeline execution with additional logging such that every time a different command executed, we’d log how long it took. Our application used logging extensively. Most of these issues occurred when we had a significant increase in user activity.

These errors would show up in our logging in the form of an AggregateException:

An error occurred while writing to logger(s). (The process cannot access the file because it is being used by another process.)

With an Inner Exception:

System.Diagnostics.EventLogInternal.InternalWriteEvent(UInt32 eventID, UInt16 category, EventLogEntryType type, String[] strings, Byte[] rawData, String currentMachineName)
System.Diagnostics.EventLogInternal.WriteEvent(EventInstance instance, Byte[] data, Object[] values):170
Microsoft.Extensions.Logging.EventLog.WindowsEventLog.WriteEntry(String message, EventLogEntryType type, Int32 eventID, Int16 category):129
Microsoft.Extensions.Logging.EventLog.EventLogLogger.WriteMessage(String message, EventLogEntryType eventLogEntryType, Int32 eventId):158
Microsoft.Extensions.Logging.EventLog.EventLogLogger.Log[TState](LogLevel logLevel, EventId eventId, TState state, Exception exception, Func3 formatter)
Microsoft.Extensions.Logging.Logger.<Log>g__LoggerLog|12_0[TState](LogLevel logLevel, EventId eventId, ILogger logger, Exception exception, Func3 formatter, List1& exceptions, TState& state):45


We’d essentially see hundreds of these errors and it would cause our application to become unresponsive and timeout requests. But—our application does not need EventSource logging, so we took the recommendation of @Dan Kroymann and removed the EventLog from the logging providers configured in Progam.cs, e.g.,

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());

You may need to reference additional nuget packages in order to use some of the logging extension methods:

Microsoft.Extensions.Logging

Microsoft.Extensions.Logging.Console

Microsoft.Extensions.Logging.Debug

Once we put the above fix in place, we stopped seeing EventSource logging issues.
