Deadlock when converting HTML to PDF

Aspose.PDF Product Family
1

Hi All,

We have noticed issue when converting HTML to PDF using Aspose.PDF version 24.7.0.0. This problem have been identified on our machines as well as in our clients’ production environments.

While processing multiple HTML files, both in single-threaded and multi-threaded scenarios, we encounter a deadlock when creating the document object using Aspose.Pdf.Document(stream, htmlOptions). This causes components of our system to stop working.

I am attaching a sample code and a screenshot from the memory dump.

Could you help us resolve this issue?
Thanks in advance,
Artur

Have you tried using 25.1 version of the API? Can you please using the latest version and see if it resolves issue. Please let us know in case you still face any issues.

Hi,
I have tried using 25.1 version and unfortunately the problem still occurs.

@asad.ali

I just ran the script using Aspose.PDF 23.6.0 (our previous version) and the problem is gone. Over 10,000 conversions were successful.

Hi @asad.ali,

this is critical issue for us, our clients rely on it in their business critical areas.
Can we prioritize it as it affects thousands of our users (and it is not minor issue, but something introduced in recent version of your product)?

Best regards,
