We have a paid license for .Net Aspose.PDF family and sometimes when we run batch processing scripts after a few files have processed successfully the Aspose S/W puts the following line on the documents:
Evaluation Only. Created with Aspose.Pdf. Copyright 2002-2017 Aspose Pty Ltd.
This is really random and when this occurs the .Net server starts throwing http 500s level errors and the whole system becomes unusable. Would you why/when this happens?
