Webservice returns empty soap-body in response to the client

Issue

• Facing an issue where the soap-based cxf webservice suddenly returns empty soap body to the client .
• Proper response is generated in the logs but that response does not get back to the client.
• This happens usually after the server is restarted . Workaround is to restart the server again.
• Response received at client:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body/>
</soap:Envelope>
