I'm currently working in a BizTalk project where we are using WCF adapters with SAP bindings to communicate with SAP. We "randomly" finds that our receive locations loose the connection to SAP. In BizTalk everything looks fine, the receive location is up and running, but when we look in SAP the connection is down.
