Invalid Section Height when I load the nth subreport

I am attempting to load multiple sub-reports into a master report document. The process is:

1. Use the RAS SDK to obtain a reference to the detail area
2. Add a section to the detail area
3. Import the subreport into the detail area
   
   

The code is pretty simple as well.

        privateReportDocument AddSubReportToParent(string subReportName, string fileName)

        {

            try

            {

                CrystalDecisions.ReportAppServer.ReportDefModel.ISCRArea detailArea = _crystalDocument.ReportClientDocument.ReportDefController.ReportDefinition.DetailArea;

                CrystalDecisions.ReportAppServer.ReportDefModel.Section section =new CrystalDecisions.ReportAppServer.ReportDefModel.Section();

                string sectionName ="Section"+ subReportName.Replace(".", "");

                section.Name = sectionName;

                section.Kind = CrystalDecisions.ReportAppServer.ReportDefModel.CrAreaSectionKindEnum.crAreaSectionKindDetail;

                section.Width = headerArea.Sections[0].Width;

                _crystalDocument.ReportClientDocument.ReportDefController.ReportSectionController.Add(section, detailArea, -1);

                _crystalDocument.ReportClientDocument.SubreportController.ImportSubreport(subReportName, _configSettings.InputPath +"\\"+ fileName, section);

                ReportDocument subreport = _crystalDocument.OpenSubreport(subReportName);

                return subreport;

            }

            catch (Exception ex)

            {

                Logger.ErrorException(this.GetReportBuilderErrorText(this.GetReportBuilderErrorText(String.Format("Unable to add subreport '{0}' from file {1} to custom Crystal Report", subReportName, fileName))), ex);

                throw;

            }

        }

However, when I attempt to load the 41st report (or sometimes greater) the ImportSubreport method throws an exception with the message, "Invalid Section Height". Note that I have one section for each report. This is to make it easier to place the subreport on in the document and on it's own page.

I cannot seem to determine what is going wrong. Why would the 41+ import fail?

I am using Crystal Reports Version for Visual Studio .NET, 13.0.8.
