Net Client Throwing Exception

Hi,

Anybody Could you help me. I generated wsdl file using (SOAP-RPC) webmethods flow service.Transport is https. I have two clients one client using .Net,Other using JAVA Axis.They installed my wsdl file into their respective clients. I noticed one problem while .Net client invoking my webService from remotely. He is execuing my flow service using his .Net client. I noticed one Exception in my Server log.

Exception is:
baseURL (Read timed out)
2005-03-30 01:52:29 PST [ISC.0088.0001E] SOAPException: [ISS.0088.9125] SOAP request does not conform to the SOAP message model
2005-03-30 01:55:30 PST [ISP.0090.0003C] MVT Started Testing before

I kept debugger in my flow service.Request , Execution is taking 3 minutes.When i Looked into documentation. Client is using Incompatible schema. Header,Body structure is not proper.

My question is what I need to do in my side.Other wise what i advise my client to do his side (He is using my wsdl file) to improve performance, wipeout above Exception.

Appreciate your help.

Thanks,
