Aspose thread running too long for some cases

Sometimes we run into java threads running too long like more than 4 hours while creating PDF file.

Here is the sample code

        com.aspose.pdf.Document doc = new com.aspose.pdf.Document("add file path");
        com.aspose.pdf.Document pdfDoc = new com.aspose.pdf.Document();

        PageCollection origPages = doc.getPages();
        PageCollection subsetPages = pdfDoc.getPages();
        for (Integer page : pages) {
            Page pageObj = origPages.get_Item(page);

Here are few stacktraces we found

Can you please define ‘pages’ variable and share source PDF file so that we may try to reproduce the same on our end.
