I have a report in MS reporting services that renders just fine to the screen (when viewing the report through the reporting services web interface), but when I go to export that to a PDF it errors.
The following YSOD is shown when trying to access the report via web services, but the report errors when rendering to PDF from the reporting services web interface as well.
Any ideas on how I can track down what is causing this issue?
Server Error in '/****' Application.

EDIT
it looks like when the report is very large (not sure what the threshold is) then the PDF fails to render. (40+ PDF pages makes it error but not 5 or less for example).
It may be a good idea to try and look at the error logs on the server that renders the report. Look to see if there is something specific occurring with RS. Can you produce the report locally from Visual Studio into a PDF?
I’ve seen similar behavior before if it is actually timing out. Should this report take a bit of time to produce? What about exporting to other formats?
