Error when using ConvertHTML in web application

Aspose.HTML Product Family
1

I’m converting an html file to pdf, using the code below. This code works fine in a console application. When I run the same code in a .NET Framework 4.8 web application, the app pool recycles and an Event Log message is written: Application popup: w3wp.exe - System Error : A new guard page for the stack cannot be created.

        using (HTMLDocument htmlDocument = new HTMLDocument(htmlFileName))
        {
            Aspose.Html.Saving.PdfSaveOptions pdfOptions = new Aspose.Html.Saving.PdfSaveOptions();
            Aspose.Html.Converters.Converter.ConvertHTML(htmlDocument, pdfOptions, pdfFileName);
        }

I am using version 22.11, which handles most files but we have encountered one that produces the same behavior, recycling the app pool.

A related issue here Error when using ConvertHTML in web application was logged, that crashes the app pool. The fix was applied and seems to fix many cases, but there still exists some HTML files that crash the app pool.NewCrashFromMsg.zip (51.8 KB)
