Is it possible to attach a debugger (e.g. Visual Studio) to your RFC server and turn on "first chance exception handling?

This sounds as if your .NET-code threw an exception that was trasfered to ABAP. You should enclose your code with a try-catch-block and write any exception to a log file, so you see when and why the exception happens (pseudo-code snippet):

public override void MyRFCServerFunction(...)

{

try

{

// do you server code here

}

catch(Exception ex)

{

MyLogfile.Write(ex);

}

}
