      Description

      I have 3 appenders in my config file for creating 3 different types of logs. I am using dynamic naming of file in each of the 3 appenders by setting the global context properties. In some cases, i need to set the log file name dynamically for just 1 appender. When i set the file name for just 1 appender, it creates another file named "null" with no data in addition to the actual logfile whose name has been set dynamically.

      <appender name="RollingFileAppenderV1" type="log4net.Appender.RollingFileAppender">
      <file type="log4net.Util.PatternString" value="Logs%property

      {applog}

      " />
      .
      .
      .
      <appender name="RollingFileAppenderV2" type="log4net.Appender.RollingFileAppender">
      <file type="log4net.Util.PatternString" value="Logs%property

      {dblog}

      " />
      .
      .
      <logger name="Logger1">
      <level value="DEBUG" />
      <appender-ref ref="RollingFileAppenderV1" />
      </logger>
      <logger name="Logger2">
      <level value="DEBUG" />
      <appender-ref ref="RollingFileAppenderV2" />
      </logger>

      In the VB.NET code i set the filename as :

      log4net.GlobalContext.Properties("applog") = "file1.log"
      Dim logobj as log4net.Ilog = LogManager.GetLogger("Logger1")
      logobj.debug("test")

      In this case it creates "file1.log" and also another empty file with name as "null". This happens only when i am setting either of the appenders filename at runtime.
      Could you please check and let me know the issue behind this.
