log4net的错误消息在日志文件中被截断

Question

I have these code:

class Program
{
    protected static ILog logger = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

    static void Main(string[] args)
    {
        try
        {
            throw new Exception("1234567890abcdefghijklmnopqrstuvwxyz");
        }
        catch (Exception exception)
        {
            logger.Error("error", exception);
        }
    }
}

when I run it from my computer, visual studio, the error in log file is

2019-09-12 14:07:19,302 [10] ERROR InspectionEmail.Program [(null)] - error System.Exception: 1234567890abcdefghijklmnopqrstuvwxyz at InspectionEmail.Program.Main(String[] args) in D:\\TFS\\XXXXXX\\Manufacturing\\Main\\PartsTracking\\InspectionEmail\\InspectionEmail\\Program.cs:line 30

when I run it from server, the error in log file is

2019-09-12 14:06:55,744 [1] ERROR InspectionEmail.Program [

why is that? what went wrong?

Answer 1

try checking if the web config part matches locally and on the server, specifically check the MaxSizeRollBackups,

  <MaxSizeRollBackups value="-1" />

Also check the maximumFileSize is not set to something very small on the server
