System error and restart not possible

Hi

I have developed the Proxy to SOAP scenario and it used to work normally as designed, But suddenly it started giving the System error and restart not possible,

I see the following error in the Runtime work bench on the Receiver CC

SOAP: response message contains an error XIAdapter/HTTP/ADAPTER.HTTP_EXCEPTION - HTTP 500 Internal Server Error

Can anyone let me know what the error is

Thanks
