How to send to multiple endpoints in wso2esb - wso2

Question

I am using wso2esb-4.8.1,
I wish to log the transaction details after response back to client.
For that I have written Proxy as well as sequence but wso2esb-4.8.1 is not supporting that with send mediator ,because I want t use load balance for every endpoint where as same logic is working in CallOUt mediator with URL option not with address endpoint .
proxy
<proxy xmlns="http://ws.apache.org/ns/synapse" name="Test_Proxy" transports="https http" startOnLoad="true" trace="disable">
<description/>
<target>
<inSequence onError="FaultSeq">
<property name="FORCE_ERROR_ON_SOAP_FAULT" value="true" scope="default" type="STRING"/>
<log>
<property xmlns:ns="http://org.apache.synapse/xsd" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" name="ProxyInRequest"
expression="/soapenv:Envelope"/>
</log>
<xquery key="ProxyRequestTransformation">
<variable xmlns:ns="http://org.apache.synapse/xsd" name="Operation" expression="//Operation/text()" type="STRING"/>
<variable xmlns:ns="http://org.apache.synapse/xsd" name="ServiceNameSpace" expression="//ServiceNameSpace/text()" type="STRING"/>
<variable name="Payload" type="DOCUMENT_ELEMENT"/>
<variable xmlns:ns="http://org.apache.synapse/xsd" name="ServiceName" expression="//Service/text()" type="STRING"/>
</xquery>
<send>
<endpoint>
<address uri="http://localhost:8081/middleware/services/test1" format="soap11"/>
</endpoint>
</send>
</inSequence>
<outSequence onError="FaultSeq">
<property name="FORCE_ERROR_ON_SOAP_FAULT" value="true"/>
<property action="set" name="RESPONSE" scope="default" type="STRING" value="true"/>
<send/>
<sequence key="AuditSeq"/>
</outSequence>
</target>
<publishWSDL key="EaiEnvelope"/>
</proxy>
In above proxy i have used default send mediator after that trying to do audit in same flow ,My client is getting response back but details are not auditing even not getting any error.
My sequence
<sequence xmlns="http://ws.apache.org/ns/synapse" name="AuditSeq"> <property name="FORCE_ERROR_ON_SOAP_FAULT" value="true" scope="default" type="STRING"/>
<property xmlns:ns="http://org.apache.synapse/xsd" name="RESULT_CODE" expression="get-property('ResultCode')" scope="default" type="STRING"/>
<property xmlns:ns="http://org.apache.synapse/xsd" name="RESULT_MESSAGE" expression="get-property('ResultMessage')" scope="default" type="STRING"/>
<property xmlns:ns="http://org.apache.synapse/xsd" name="REFERENCE_ID" expression="get-property('ReferenceID')" scope="default" type="STRING"/>
<property xmlns:ns="http://org.apache.synapse/xsd" name="FAULT_DETAILS" expression="concat(get-property('ERROR_CODE'),get-property('ERROR_MESSAGE'))" scope="default" type="STRING"/>
<payloadFactory media-type="xml">
<format>
<open:processRequest xmlns:open="http://www.openuri.org/">
<aud:Auditor xmlns:aud="http://jhm.kkk.fff/Auditor">
<aud:Request>
<aud:Operation_Name>processRequest</aud:Operation_Name>
<aud:Auditor_InputData>
<aud:Result_Code>$1</aud:Result_Code>
<aud:Result_Message>$2</aud:Result_Message>
<aud:Reference_Id>$3</aud:Reference_Id>
</aud:Auditor_InputData>
</aud:Request>
</aud:Auditor>
</open:processRequest>
</format>
<args>
<arg evaluator="xml" expression="get-property('RESULT_CODE')"/>
<arg evaluator="xml" expression="get-property('RESULT_MESSAGE')"/>
<arg evaluator="xml" expression="get-property('REFERENCE_ID')"/>
</args>
</payloadFactory>
<header name="Action" scope="default" value="http://www.openuri.org/processRequest"/>
<send>
<endpoint>
<address uri="http://localhost:8081/middleware/services/AuditService" format="soap11"/>
</endpoint>
</send>
<log>
<property name="aftersend" value="message going out or not"/>
</log>
</sequence>
With above send mediator is not working .But after send my log is printing.
If i replace send mediator with CallOut URL option its working fine.
<callout serviceURL="http:///localhost:8081/middleware/services/AuditService">
<source type="envelope"/>
<target key="IsThisResponse"/>
</callout>
In above we are not able to use loadbalancing.For that I trying for send mediator.
Is any way to do this.
I thouhgt wso2esb-4.8.1 is become stable but again its having drawbacks.
Thanks in advance.

Please try by changing the send mediator in your proxy as mentioned here it may help you
<send receive="AuditSeq">
<endpoint>
<address uri="http://localhost:8081/middleware/services/test1" format="soap11"/>
</endpoint>
</send>
