I am using a RollingFileAppender , and my own custom layout. My application
is multithreaded. Each thread will generate unique random data and is
supposed to log it using log4net framework. However if I create multiple
threads in quick succession I notice stale data in my logs , this goes away
if each thread sleeps for 50 ms before logging. I am not able to figure out
a solution to this issue or find its cause please do help me.

My logging function looks like this:


    log4net.ThreadContext.properties["randomGeneratedData"] =
randomGeneratedData;
    private ILog myLog =
           LogManager.GetLogger(typeof(LogTest));
    using (log4net.NDC.Push("ndcTest1"))
    {
        using (log4net.NDC.Push("ndcTest2"))
            {
                myLog.Info("myLogTest");
            }
    }





Result of logging:

       NDC = "ndcTest1 ndcTest2" , randomGeneratedData = rad1
       NDC = "ndcTest1 ndcTest2" , randomGeneratedData = rad2
       NDC = "", randomGeneratedData = rad2

and so on ...


I tried to clear log4net.ThreadContext.Properties before filling it again ,
but it was of no use. Please help.
