ContextSwitchDeadLock

Hi,

I am trying to generate a PDF as a MemoryStream using the HtmlToPdfResult object. It seems that the Render method works on small webpages, but doesn't work on large webpages. I have placed two examples below.

Does anyone have an idea what the problem might be and how this can be fixed?

Kind regards,

Pierius
