2685804 - Downloading large PDF spools to frontend does not complete or causes SAPGUI hang

• You need to download a very large ADS PDF spool in SP01 (with hundreds or even thousands of pages), to a single PDF file on your frontend PC.  You use, for example, menu option 'Export as PDF' (note 1717357) or print to a frontend printer with SAPPDFPrint (KBA 1602625).
• 1717357 - Download spool requests from SP01
• 1602625 - Download Adobe PDF spool with many parts to one PDF file on Frontend 
• Results may be inconsistent.  For example sometimes the download may complete, other times it does not.
• The SAP GUI session may hang or crash.  There may be a GUI pop-up error such as "maximum work process hold time exceeded".
• If you capture a frontend print trace (KBA 1780896), the following errors may be seen in the sapwin log file:
• ** Calling pdfprint->openDoc
• Error: This file cannot be found.
