Compress/Optimize PDF documents using Aspose.PDF for .NET - StackOverFlowException occurs

Aspose.PDF Product Family

Hi,
I am using aspose.pdf (v17.6) to compress pdfs. It works fine with small files, but it has “StackOverflowException” for big files greater than about 130MB. I tested it with the latest aspose.pdf version ( v19.7 ), but still had the same issue. Any suggestions?

using (Aspose.Pdf.Document pdfDocumentTemp = new Aspose.Pdf.Document(inputFile))
{
pdfDocumentTemp.OptimizeSize = true;
pdfDocumentTemp.OptimizeResources(new Aspose.Pdf.Document.OptimizationOptions()
{
RemoveUnusedStreams = true,
RemoveUnusedObjects = true,
LinkDuplcateStreams = true,
AllowReusePageContent = true,
UnembedFonts = false
});

                        pdfDocumentTemp.Save(tempFileName);                            
                    }

Regards,
JS

We were able to notice that memory consumption was hiking continuously while processing your document. However, we were unable to notice StackOverFlowException due to suspended system during testing. Would you kindly share the stack trace of exception which you have received at your end. We will further proceed to assist you accordingly.
