Thank you, Scott, for telling me to get my nose out of my script.
<grin />

I think that that *may* have been the problem:  on my local router, I
opened all inbound ports from the iSeries, and I have just run three
successful downloads in succession.  I say only "may" because
(*) Until earlier this week, the download was working routinely anyway.
(*) My router is home-grade, and while the (html) display suggests it is
running IPTABLES, it protects from the details of the rules.  Sigh!
(*) I do not understand just why the download would fail between one
member and the next.  Still, nowhere is it written that I shall
understand everything.  It is easy enough to imagine that the router
failed to clean up its table of related connections when connections
were closed, and then it is easy to throw around words like "table
overflow" and so forth.

Anyway, the problem is in abeyance for now, and for that I thank you.

Cheers,
Terry.
