No, we should not assume HTTP server is running.

So, wpkg.js would have to connect somewhere: http://wpkg.server.org/wpkg-log.php?query and expect a number (like 10, for 10 running installations). If the number is greater than, say, 15 (configurable), wait for 30 seconds. wpkg.js should report its actions every 15-60 seconds or so - if a given host doesn't report anymore, consider the installation successful (host died, ended installation etc.) Hmm, perhaps, much more has to be thought. Still, I'm not persuaded by this approach. If the OP has a fat server as he says, it shouldn't suffer in that way with a 90 MB file. The file should be buffered/cached fully by the operating system, and served from RAM. With small devices serving as file servers, installing 70 clients concurrently is not a great idea (although it happened to me to installed ~30-40 machines, operating system + software, off a 2.4 GHz machine with 256 MB RAM - still, it went fine). So I guess, the OP should look more carefully at his server's configuration. -- Tomasz Chmielewski http://wpkg.org ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
