'Keep Header' Option in SOAP sender adapter not working

Hi all

I have exposed a webservice using a SOAP sender adapter in XI. A SOAP client is sending request to this service.

The SOAP request has some elements in the header like wssecurity and ws addressing tags.

When I remove the header elements and send the request my scenario works as expected but when I include the header fields I get a time out in my soap client application and cannot see any message, any where on XI. Can somebody help me understand why this is happening.

Thanks

Dilip
