Jboss is truncating log file contents when it is restarted

In order to avoid truncating server.log file contents when restarting jboss, change jboss-log4j.xml FILE Appender class.

<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="50MB"/>
     <param name="MaxBackupIndex" value="20"/>

     <layout class="org.apache.log4j.PatternLayout">
       <param name="ConversionPattern" value="%d %-5p [%c] %m%n"/>
     </layout>
   </appender>

Set value of the Append parameter to "true"

  1. I found the service that was filling up the d:\kronos\jboss\bin\stderrwfc.log and shut it down in the log config.

    I'm looking into how to set the service to truncate that log back to zero when I restart the service. At the moment it is set to keep the log file and append on a restart.

    We're close. If anyone know "log4j" configuration over there, that appears to be the key.

  2. If stderrwfc.log is server log file and can be managed via log4j, as far as i know param name="Append" value="false" will do the trick.
