If SODE disconnects during a flight, it cannot possibly have anything to do with GSX.
The only time when GSX and SODE interacts are when you enter an airport ( GSX will ask SODE if there are already SODE jetways on that airport ), and when you activate a jetway, so GSX ask SODE to animate it.
So, it seems you are reporting to entirely different issues, one that might be related to GSX, the other that is not. For 413x3, please indicate the airport used, and if they use SODE XML jetways or GSX/SODE jetways.
