Jacque,

What error does libURL report?  Can you get around this by trying to  
download the url that caused the error again (trying a max of 3 times  
or so)?  I ask because I have download over 1,000 files consecutively  
on an OS X machine with Mail running and I didn't notice any  
problems.  I use

load URL "myURL" with message "downloadComplete"

and check for errors in downloadComplete.  If a timeout (param 2 is  
"timeout") or an error occurred (param 2 is "error") and  
libURLErrorData() reports "socket closed before end of file", "error  
socket is open" or just "error" then I try to download the URL a max  
of 3 times.  I've had excellent results with this method on both OS X  
and Windows.
