"Server Instance Error" in SOAP PI Adapter engine

Hi,

While sending a message from ECC system to Integration server through PI, message getting failed.

The message fails at SOAP adapter engine while message passing from PI to Integration server through adapter. The error is

"SOAP: response message contains an error XIAdapter/PARSING/ADAPTER.SOAP_EXCEPTION - soap fault: OSBE01 server instance error : Exception occurred during execution on the exchange: Exchange[Message: javax.xml.transform.dom.DOMSource@2a48ea80]"

What are the possibilities for the above error to occur? Could anyone please explain?

Thanks!

Regards,

Gopi
