We do have a production including a SOAP.OutboundAdapter that make a request to a .NET WCF Service. The response from that service vary in size. When it come to large one, we talk about maybe 8000 records (with 6-8 attributes per record) in xml, the adapter always give a timout. Even if we put a high number of seconds or set -1. After 1 1/2h still nothing get back. It's just standing there and waiting for ever.
