java如何防止log4j（1.2.14版）Ayncapender记录不必要的文本

Question

我试图在我的应用程序中使用带有AsyncAppender的log4j。见下文：

<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/" debug="true">

    <appender name="asyncAppender" class="org.apache.log4j.AsyncAppender">
        <param name="BufferSize" value="500"/>
        <appender-ref ref="consoleAppender"/>
        <appender-ref ref="fileAppender"/>
    </appender>

    <!-- file appender -->
    <appender name="fileAppender" class="org.apache.log4j.RollingFileAppender">
        <param name="File" value="C:/IFFC-Home/logs/iffcserver.log" />
        <param name="MaxBackupIndex" value="5" />
        <param name="MaxFileSize" value="5MB" />
        <layout class="org.apache.log4j.PatternLayout">
            <!-- The default pattern: Date Priority [Category] Thread Message -->
            <param name="ConversionPattern" value="[%d{ISO8601}] [%t] [%-5p] %c: %m%n"/>
        </layout>
    </appender>

    <!-- console appender -->
    <appender name="consoleAppender" class="org.apache.log4j.ConsoleAppender">
        <layout class="org.apache.log4j.PatternLayout">
            <!-- The default pattern: Date Priority [Category] Message -->
            <param name="ConversionPattern" value="[%d{ISO8601}] [%t] [%-5p] %c: %m%n"/>
         </layout>
     </appender>

     <category name="com.oberon">
         <priority value="TRACE"/>
     </category>

     <root>
         <priority value="INFO"/>
         <appender-ref ref="asyncAppender"/>
     </root>
</log4j:configuration>

应用程序派生出另一个线程来对应用程序进行日志监视

在将我的应用程序部署到Wildfly 8.1并启动它之后，我确实看到我的日志被记录在控制台窗口和日志文件中，但我最终收到了大量这样的消息：

[2014-10-22 17:00:36,966] [AsyncAppender-Dispatcher-Thread-85] [INFO ] stdout: [2014-10-22 17:00:36,820] [AsyncAppender-Dispatcher-Thread-85] [INFO ] stdout: [2014-10-22 17:00:36,719] [AsyncAppender-Dispatcher-Thread-85] [INFO ] stdout: [2014-10-22 17:00:36,694] [AsyncAppender-Dispatcher-Thread-85] [INFO ] stdout: [2014-10-22 17:00:36,671] [AsyncAppender-Dispatcher-Thread-85] [INFO ] stdout: [2014-10-22 17:00:36,649] [AsyncAppender-Dispatcher-Thread-85] [INFO ] stdout: [2014-10-22 17:00:36,625] [AsyncAppender-Dispatcher-Thread-85] [INFO ] stdout: [2014-10-22 17:00:36,599] [AsyncAppender-Dispatcher-Thread-85] [INFO ] stdout: 

这一切都在一行中，同样的事情一遍又一遍地重复着。只有在尝试使用AsyncAppender时才会发生这种情况

我还打开了log4j调试，这是它在Wildfly服务器日志中打印出来的内容：

我是否缺少正确配置并删除所有额外重复消息的功能
