I've also had OOM errors with SA installed. It even happens at a fixed spot, when I'm landing somewhere between the parachutes fully deploying at 500m and the ground. I'm not sure what I do to debug this, and the error log does not mention SA specifically, just the OOM errors. I'll try and enable/disable my mods some more and see if i can find out anything. Edit: I've landed succesfully several times with only SA running, so it may be something else. Some sort of conflict with other mods, or just a one off thing.
