We have SSRS reports that contain several charts. These reports are rendered through a custom .NET MVC app to PDF, or to PowerPoint using Aspose slides.
We recently moved the reports from a 2005 SSRS server to a 2008 R2 SSRS server. The reports mostly work well. One report, however, is throwing the following error whenever the number of pages is large (19) and we try to render to PowerPoint (PDF works okay).
The same report renders fine to PowerPoint if different filters are applied that result in fewer pages.
Any ideas? I'm not sure if this is a SSRS issue or Aspose or .NET. Thanks in advance.
