FATAL 11 when trying to get Features Table from Geodatabase

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

And here is the build enviroment

 

Visual Studio 15.7.1
Xamarin 4.10.0.442
Xamarin.Android SDK 8.3.0.19
JDK 1.8.0_172 (32 bit version)
Android SDK Tools 25.2.5
Android SDK Platform-tools 27.0.1
Android SDK Build-tools 25.0.3, 23.0.3
SDK Platforms Installed
8.0 (API 26)
7.1.1 (API 25)
6.0 (API 23)

Esri Runtime 100.2.1

 

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.
