Evaluation watermark intermittently displayed

We have a web app and worker app that use Aspose. We intermittently see an evaluation watermark on our PDF documents. We make heavy use of multi-threading code to work with PDF documents. Every so often in production we are seeing the evaluation watermark. Please help.

Thank you for contacting support.

Please ensure that the license is applied once per application which can also be validated with Document.IsLicensed property. The evaluation watermark means problem with setting the license.
