[Nika Layzell [:nika] (ni? for response)]

These crashes don't seem to happen very often and are quite inconsistent when looking through crashes as to how they would be caused, which makes it very difficult to figure out what could be happening here. Marking as S3 for now, as there's fairly low frequency, and I don't think this is actionable unless rates pick up & we find more information.
