SYMPTOMS
On a computer that is running Microsoft BizTalk Server 2004, you notice that many Csc.exe processes may be running. These many Csc.exe processes may use lots of CPU time and memory resources.



CAUSE
This problem occurs if all the following conditions are true:  The BizTalk Server orchestration uses a Web service.  The Web Service method that is called within the orchestration uses the SoapRpcMethod attribute. For example, the Web Service method uses code that is similar to the following: [WebMethod] [System.Web.Services.Protocols.SoapRpcMethod]  You run multiple instances of this orchestration.

This problem occurs because of a problem with the BizTalk Server 2004 SOAP Adapter. When the SoapRpcMethod attribute is associated with a Web Service method, the client proxy component of that method uses remote procedure call (RPC) encoding. The SOAP Adapter does not optimize client calls to XML serialization when you use RPC encoding.

This problem does not occur if the Web Service method uses the SoapDocumentMethod attribute.
