It's already there in log4j :) It's commented out in the jboss-log4j.xml:

  | <!-- A size based file rolling appender
  |    <appender name="FILE" class="org.jboss.logging.appender.RollingFileAppender">
  |      <errorHandler class="org.jboss.logging.util.OnlyOnceErrorHandler"/>
  |      <param name="File" value="${jboss.server.log.dir}/server.log"/>
  |      <param name="Append" value="false"/>
  |      <param name="MaxFileSize" value="500KB"/>
  |      <param name="MaxBackupIndex" value="1"/>
  | 
  |      <layout class="org.apache.log4j.PatternLayout">
  |        <param name="ConversionPattern" value="%d %-5p [%c] %m%n"/>
  |      </layout>	    
  |    </appender>
  |    -->

I think it might make sense to have this size based rolling file appender (with Append=true) as default *even in production* instead of the time based appender. This way we don't have to worry about the log file growing to a large size even in production environment (imagine the user application doing a lot of logging or some other reason) during a day. 
All we have to do is switch the "FILE" appender in jboss-log4j.xml to RollingFileAppender and set the maxfilesize and maxbackupindex to a reasonable value and also set append =true.

Thoughts?
