Export to PDF Issue (SSRS 2012 with Integration SharePoint 2013)

Question

Problem Description: We have an operational report that returns around 43,000 records, based on a stored procedure.  The Stored Procedure itself runs pretty quickly (under ~15 seconds).The report renders in 20 seconds.
However, we get an error like “Sorry, something went wrong” (see below) approximately 2 minutes after we choose/select the PDF as a rendering extension for export. The download of the .PDF never starts.
Sorry, something went wrong
An unexpected error has occurred.

The 2 minutes is what I get from the execution log... it is actually 122 seconds for timerendering. As for the rs trace log from the web server, see below...

Things Also Done
1) I also tried exporting the report through excel and found no issues (it exports successfully and no issue when i open the file). The size of the exported excel (.xlsx) is 4.28MB. The timerendering value for export to excel is approx. 77 seconds.
2) I also tried creating email subscription (PDF as the rendering format) for that report and it works successfully. The size of the attached PDF from the email is approx. 1.43 MB. I can also open that PDF file with no issue. And the size of the email with
the attached PDF file is approx. 1.48 MB.
That all said, we would like to seek for your assistance to determine what is causing the failure of exporting the report to PDF issue directly from the reporting site. (Let me remind you that the email subscription for the same report with attached
PDF works with no issue)

Answer 1

Hi roel2000,
According to your description, you get error when exporting the report into PDF. It works properly when exporting in excel or PDF format within E-mail subscription. Right?
In Reporting Services, the Excel and MHTML(e-mail subscription) render extensions are soft page break renderers. The PDF render extension is hard page break renderer. It has different render behavior between these two kind of renders. This might cause the
error. Since we are not clear about your report structure, please refer to rules in the link below and do the troubleshooting.

If you have any question, please feel free to ask.
