I too have the same problem. Tried with 50,000 records and the page crashed, but no errors reported. Further troubleshooting the problem, I noticed that the physical size of the generating shapefile matters. When I tried to download 20,000 records WITHOUT properties, it downloaded successfully. But when I added couple of simple properties to those features and tried again it failed.

So, I guess the code fails once the download size exceeds a limit.

Yea, Seems like a size limitation of JSZip.
