A case of malformed request from W3

Check if the service is able to recieve the request using SOAP UI, also check if the datatypes between server and client calls match.

I suspect that your issue involves the WCF binding configuration. In particular, the maxReceivedMessageSize value and/or the readerQuota settings. If you provide your client/server bindings (or the entire relevant sections of the configuration file, we could provide better guidance.)

Note: you may want to enable WCF tracing, if you have not already, to help determine the cause of the issue. Reference: http://msdn.microsoft.com/en-us/library/ms733025(v=vs.110).aspx

Your service configuration does not show the service definition or the service bindings, so it is hard to tell if the maxReceivedMessageSize value and/or the readerQuota settings on the service match the client. – Seymour Mar 31 '14 at 13:05
