Windows Service restart causing _001, _002, _003 files.

I currently have the following Ilogger configuartion.

return new LoggerConfiguration().Enrich.With().Filter.ByExcluding(ev => !fixieOptions.IsSerilogEnabled).MinimumLevel.Debug().WriteTo.Async(appender => appender.File(Path.Combine($"{AppDomain.CurrentDomain.BaseDirectory}\..\logs", "telemetry", "telemetry..log"), rollingInterval: RollingInterval.Day,outputTemplate: "{UtcTimestamp}|{Level:u3}|{Message:lj}{NewLine}{Exception}")).CreateLogger();

Each time I restart my windows service a new file is created and appended with a sequence number. The issue is that on another windows service the same configuration is used and when that service is restarted NO new file is created. How do I prevent the _001..._00n sequence files from getting created. I want a single file per day.

If multiple services are writing to the same path, you'll need to add shared: true to the RollingFile configuration.

Otherwise, it's likely that the file is still being held open by another process, perhaps due to overlapped shutdown/startup, because the logger isn't being closed/disposed appropriately, or because more than one logger instance is being created per application run. Do any of these suggest a cause? Cheers!

That solved it I just needed to increase the wait time between when the service was shutdown and then restarted.
