Please Help me for ErrorHandler in log4cxx

Hi friends
  I am using the Log4cxx in my application, But got a big problem at error handler.
 If suppose logs r going to record at server side and server goes down ,then throw  the FALLBACK ie handler we can divert the logs.
 I wrote the xml file for error handler,if one server goes down then divert the output to other server ,If logs r not diverting to handler server once the PRIMARY goes down.

My xmlconfigurator is as follows

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j='http://jakarta.apache.org/log4j/'>
        <appender name="PRIMARY" class="org.apache.log4j.net.SocketAppender">
             <param name="RemoteHost" value="localhost"/>
             <param name="Port" value="6044"/>
             <param name="ReconnectionDelay" value="5000"/>
             <errorHandler class="org.apache.log4j.varia.FallbackErrorHandler">
                 <param name="logger" value="root"/>
                 <root-ref/>
                 <logger-ref ref="Log_debug"/>

                 <appender-ref ref="FALLBACK"/>
            </errorHandler>
        </appender>
