We had been experiencing this crash for a quite while for ArcGIS Runtime SDK app, Nov, 2015. The .geodatabase sized about 2.5GB+, about 90 layers.
Further narrowed down to one particular layer which crashes, has 60k+ features.
Another fact is it only crashes when loading into a MapView object, but not when loading into a FeatureLayer object.
So the solution is likely to load this large layer at a level of lower details. This sounds like obvious once the cause is clear.
