FATAL 11 when trying to get Features Table from Geodatabase

NathanWestfall1

From time to time, I get in our Xamarin.Android app a fatal 11 when loading a features table.

Here is the C# code

public static Esri.ArcGISRuntime.Data.GeodatabaseFeatureTable GetStreetFeatureTable(Esri.ArcGISRuntime.Data.Geodatabase gdb, string tableName)
{
    GeodatabaseFeatureTable table = gdb.GeodatabaseFeatureTable(tableName);

    if (table == null)
    {
        table = gdb.GeodatabaseFeatureTable(0);
    }

    return table;
}

Here's the crash

The only thing I can think of that I might be able to prevent, is calling this function from 2 threads at the same time.  We have different feature layers we use and it is possible that from time to time two threads could call it at the same time.

Did you try this with a lock statement to try and prevent it from doing this from multiple threads? Did it help?

Is there any way you can provide us with a reproducer? The above unfortunately doesn't give me much to go on.
