Using with org.apache.log4j.RollingFileAppender

[dannyellis-zz]

I'm trying to get this working with a RollingFileAppender, but it doesn't seem to be taking. Can't see anything useful in the log file but was wondering if something looked strange about my log4j.xml file

<appender name="FILE" class="org.apache.log4j.RollingFileAppender">
     <errorHandler class="org.apache.log4j.helpers.OnlyOnceErrorHandler"/>
     <param name="File" value="${jboss.home.dir}/log/server.log"/>
     <param name="Append" value="true"/>
     <param name="Threshold" value="TRACE"/>
     <param name="MaxFileSize" value="10000KB"/>
     <param name="MaxBackupIndex" value="5"/>
     <layout class="net.logstash.log4j.JSONEventLayoutV1"/>
   </appender>

Possibly I have the same issue. I have set the MaxFileSize to 100KB but it just expands straight past that. It does not throw an error so the parameter is accepted as valid?
