导出war包部署在tomcat/webapps下，并设置为默认项目，<Context docBase="logbackweb" path="" reloadable="true"/>，结果发现logback配置中
----------------------------------------------------------------
<appender name="FILE1" class="ch.qos.logback.core.rolling.RollingFileAppender">
<File>D:/cqinfo.log</File>
<rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
<maxIndex>100</maxIndex>
<FileNamePattern>d:/cqinfo.log.%i</FileNamePattern>
</rollingPolicy>
<triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
<MaxFileSize>5MB</MaxFileSize>
</triggeringPolicy>

<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<pattern>%d

[%m] %n</pattern>
</encoder>
</appender>
----------------------------------------------------------------------
5MB的控制失效了，有人遇到过么？
看了下logback源码是在rename当前活动文件和当前活动文件.1文件时失败了，
case NONE:
util.rename(getActiveFileName(), fileNamePattern
.convertInt(minIndex));
break;
有人遇到过这个问题么？有人解决了么？
