             Project: logback
          Issue Type: Bug
    Affects Versions: 1.2.3, 1.1.11
         Environment: <?xml version="1.0" encoding="utf-8"?>

<configuration> 

 <property name="LOG_HOME" value="d:/imgtest/log"/> 

 <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> 
 <append>true</append>

 <Encoding>UTF-8</Encoding> 
 <layout class="ch.qos.logback.classic.PatternLayout"> 

 <pattern>%d\{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger\{50} - %msg%n</pattern>

 <append>true</append>

 <Encoding>UTF-8</Encoding> 
 <file>$\{LOG_HOME}/log.log</file>
 <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
 <!-- rollover daily -->
 <fileNamePattern>$\{LOG_HOME}/log-%d\{yyyy-MM-dd}.%i.log</fileNamePattern>
 <!-- each file should be at most 100MB, keep 60 days worth of history, but at most 20GB -->

When I use RollingFileAppender and SizeAndTimeBasedRollingPolicy to set <append>true</append> and <file>log.log</file> at the same time, but when I stop and restart on the same day, the original contents of the log.log file are emptied, but the original content does not generate a rolling file, and you can't find the original content anywhere.
