If your station has reaction wheels and the ship you dock also has reaction wheels, especially at different angles, it's easy to end up with an argument about which way is up and who should be pointing where.
I've had stations tear themselves apart over this sort of thing.
Two things you can do - one is to make sure you don't have SAS turned on for your station when you dock to it (the ISS does this), and the other is to disable reaction wheels and turn off RCS on your docked ship the moment you dock, before the argument can begin.
