iis express worker process has stopped working on any geometric/topologic process on server. fault module name : ExtTopoEngine.dll

Hi. I have been developing arcgis desktop applications for a long time. İ was using arcgis 9.3 for my applications. We upgraded to arcgis 10.3.1 now. But i have an error on my web service(.asmx). When i do any kind of geometric process i get the following iis error.

"iis express worker process has stopped working". error occurs on exTopoEngine.dll

Even this very simple code as below throws this error on topologicOperator.Simplify(); if i skip simplfy, it throws the same iis error on IPolygon polygon = topologicalOperator.Buffer(1) as IPolygon;.

ESRI.ArcGIS.RuntimeManager.Bind(ESRI.ArcGIS.ProductCode.Desktop);

AoInitialize init = new AoInitialize();

if (init.IsProductCodeAvailable(esriLicenseProductCode.esriLicenseProductCodeArcServer) == esriLicenseStatus.esriLicenseAvailable)

init.Initialize(esriLicenseProductCode.esriLicenseProductCodeArcServer);

else

throw new Exception("ESRI ArcGIS Server License is unavailable or has failed");

IPoint[] points = new IPoint[5];

for (int i = 0; i < points.Length; i++)

{

points = new PointClass();

}

points[0].PutCoords(0, 0);

points[1].PutCoords(0, 10);

points[2].PutCoords(10, 10);

points[3].PutCoords(10, 0);

points[4].PutCoords(0, 0);

IPointCollection4 pointCollection = new PolygonClass();

IGeometryBridge geometryBride = new GeometryEnvironmentClass();

geometryBride.AddPoints(pointCollection, ref points);

IArea area = pointCollection as IArea;

ITopologicalOperator topologicalOperator = pointCollection as ITopologicalOperator;

topologicalOperator.Simplify();

IPolygon polygon = topologicalOperator.Buffer(1) as IPolygon;

area = polygon as IArea;

We have the same / a similar problem, also after upgrading to 10.3.1.

Here IIS (express and regular IIS) also crashes because of ExtTopoEngine.dll

In the Windows log I could see that ExtTopoEngine.dll is the reason of the crashes.

Faulting module path: C:\PROGRAM FILES (X86)\ARCGIS\DESKTOP10.3\BIN\ExtTopoEngine.dll

We are also calling a method on topologyOperater, altough we are calling "ConstructUnion" when it crashes.

This is our complete code:

public static object MakeUnionGeom(dynamic geoms)

{

List<IGeometry> iGeoms = ((List<object>)geoms).Cast<IGeometry>().ToList();

IGeometry geometryBag = new GeometryBagClass();

IGeometryCollection geometryCollection = geometryBag as IGeometryCollection;

for (int i = 0; i < iGeoms.Count; i++)

{

IGeometry shp = iGeoms;

object missing = Type.Missing;

geometryCollection.AddGeometry(shp, missing, missing);

}

ITopologicalOperator unionedPolygon = new PolygonClass();

unionedPolygon.ConstructUnion(geometryBag as IEnumGeometry);

return unionedPolygon as IPolygon;

}
