log4j2滚动策略未按预期工作

Question

我有一个Log4j2.xml定义为：

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="DEBUG">
    <Properties>
        <Property name="log-path">E:/MLM/MLMDomain/servers/${sys:weblogic.Name}/logs</Property>
    </Properties>
    <Appenders>
        <RollingFile name="RollingFile" fileName="${log-path}/MLMServices.log" filePattern="${log-path}/MLMServices-%d{yyyy-MM-dd}-%i.log" >
            <PatternLayout>
                <pattern>%d{dd/MMM/yyyy HH:mm:ss.SSS} [%-5level] [%c{1}] %m%n</pattern>
            </PatternLayout>
            <Policies>
                <SizeBasedTriggeringPolicy size="1 MB" />
            </Policies>
            <DefaultRolloverStrategy max="30"/>
        </RollingFile>
    </Appenders>
    <Loggers>
        <Logger name="root" level="debug" additivity="false">
           <appender-ref ref="RollingFile" level="debug"/>
        </Logger>
        <Root level="debug" additivity="false">
            <AppenderRef ref="RollingFile"/>
       </Root>
    </Loggers>
</Configuration>

据我所知，当我的日志文件达到1MB时，它应该会滚动到新的日志文件。要滚动的文件数应为30。然而，如果你看看我下面的日志，有超过40个，所有最新的都接近30MB。当前日志文件MLMServices。日志记录了从2016年4月13日至今的条目。事实上，最后几个日志文件是MLMServices-2016-05-24-4。日志，MLMServices-2016-05-24-3。日志等包含2016年4月13日的条目。创建新日志文件时，它会复制上一个日志文件中的条目，然后追加更多条目。因此，每一个新的日志文件都会比前一个略大。

这不是我想要的行为。我只希望每个日志文件被限制在1MB，我想保留最多30个日志文件。我在配置中哪里出错了？

提前谢谢

编辑：我实际上已经指定log4j2在weblogic.xml

您应该检查应用程序之外是否有其他东西正在访问MLM服务。日志在Windows上，如果无法获得独占锁，文件重命名和删除将失败。
