Connector dies
If your connector dies, check the following:
Check that threads are being spawned by the RFC Server Module. Verify that the NumberOfListeners property is set properly. For more information, see the
"NumberOfListeners"
..
Verify that the RFC program ID is set up so that the RFC Server Module registers itself with the SAP Gateway. For more information, see the
"RfcProgramId"
and
