I kinda hinted at chunking, jd core is not good with many chunks. slighest issue with one of the connection all the good ones are terminated, and download is restarted just to resume one of the broken connections.
Also note that zippy used to fight us bad, and plugin isn't designed to give good error feedbacks. its all set to wait, which I didn't allude to before, which is probably the issue for never giving up. That said script solution might not be required if you use less chunks assuming that the issue is that and not javascript trickery.
