arcengine 内存不足问题？

小批量数据没发现这个问题，今天运行数据量几千，内存就满了，程序直接崩溃，麻烦哪位大神帮忙看看，代码如下：

 IFeature pFeature = pFeatureCursor.NextFeature();

            IGeometry pFirstGeometry = new PolygonClass();

            while (pFeature != null)

            {

                IGeometry pGeometry = pFeature.ShapeCopy;

                ITopologicalOperator pTopologicalOperator = pFirstGeometry as ITopologicalOperator;

                pFirstGeometry = pTopologicalOperator.Union(pGeometry) as IPolygon;

                pFeature = pFeatureCursor.NextFeature();

  IFeature pFeatureSecond = pFeatureCursorSecond.NextFeature();

            while (pFeatureSecond != null)

            {

                IFeature pCopyFeature = pFeatureSecond;

                IGeometry pSecondGeometry = new PolygonClass();

                pSecondGeometry = pFeatureSecond.Shape;

                ITopologicalOperator pTOSecond = pSecondGeometry as ITopologicalOperator;

                pSecondGeometry = pTOSecond.Intersect(pFirstGeometry, esriGeometryDimension.esriGeometry2Dimension) as IPolygon;

                IGeometry pSecondGeometry2 = new PolygonClass();

                pSecondGeometry2 = pFeatureSecond.Shape;

                ITopologicalOperator pTOSDifference = pSecondGeometry2 as ITopologicalOperator;

                pSecondGeometry2 = pTOSDifference.Difference(pSecondGeometry) as IPolygon;

                if (pSecondGeometry2.IsEmpty)

                {

                    pFeatureSecond.Delete();

                }

                else

                {

                    pFeatureSecond.Shape = pSecondGeometry2;

                    for (int EraseFieldCount = 0; EraseFieldCount < pFeatureSecond.Fields.FieldCount; EraseFieldCount++)

                    {

                        if (pCopyFeature.Fields.get_Field(EraseFieldCount).Name != "Shape" && pCopyFeature.Fields.get_Field(EraseFieldCount).Name != "FID")

                        {

                            var pValue = pCopyFeature.get_Value(EraseFieldCount);

                            listBox1.Items.Add(pValue);

                            pFeatureSecond.set_Value(EraseFieldCount, pValue);

                        }

                    }

                    pFeatureSecond.Store();

                }

                pFeatureSecond = pFeatureCursorSecond.NextFeature();

            }
