Serilog creates a new file after 2 KB

Question

I am using rolling file sink.

Following is my code of initialization:

Serilog.Log.Logger = new LoggerConfiguration()
            .WriteTo.RollingFile(@"L:\logs\Api-{Date}.txt", fileSizeLimitBytes: null)
            .CreateLogger();

Here is the line to log:

Log.Information(message);

But after 2 KB, it creates a new file.

I don't know what's going wrong.

Update

This is my logger class:

public class Logger
{
    public Logger()
    {
        Serilog.Log.Logger = new LoggerConfiguration()
            .MinimumLevel.Verbose()
            .WriteTo.RollingFile(@"L:\logs\Api-{Date}.txt", fileSizeLimitBytes: null)
            .CreateLogger();
    }

    public void Log(LogRequestParameters logRequestParameters, LoggingLevels loggingLevel)
    {
        var message = JsonConvert.SerializeObject(logRequestParameters);

        switch (loggingLevel)
        {
            case LoggingLevels.Verbose:
                Serilog.Log.Verbose(message);
                break;

            case LoggingLevels.Debug:
                Serilog.Log.Debug(message);
                break;

            case LoggingLevels.Information:
                Serilog.Log.Information(message);
                break;

            case LoggingLevels.Warning:
                Serilog.Log.Warning(message);
                break;

            case LoggingLevels.Error:
                Serilog.Log.Warning(message);
                break;

            case LoggingLevels.Fatal:
                Serilog.Log.Fatal(message);
                break;
        }
    }
}

This is my caller class:

public class Caller
{   
    logRequestParameters.DateTime = DateTime.Now.ToString();
    logRequestParameters.Level = "Debug";
    logRequestParameters.MachineName = Environment.MachineName;
    logRequestParameters.Type = "Request";
    logRequestParameters.Request = request;

    Logger logger = new Logger();

    logger.Log(logRequestParameters, LoggingLevels.Information);
}

The code is creating a new logger instance for each event. You need to create a single logger and use it for each logging call.

There is some further information on the lifecycle of Serilog loggers in the documentation.
