I'm reasonably sure I've found the 'culprit'.
Two settings in SODE v1.7.1 - Enable Aircraft State Triggered Auto-Docking and Enable Ai Traffic Detection were both enabled.
I've set them both to disabled and the repetition of restarts has ceased.
Yes, this worked for me as well. I do not accept this as a proper solution though, as having AI dock themselves is hugely immersive. This is a very frustration problem that so many people have and I wish the developer was more interested in solving.
