This sounds like an Internet configuration problem, or a timeout problem.
Neither PmWiki nor Apache nor PHP are responsible for "Cannot find server"
errors.

It could also be a caching problem--Internet Explorer or some intermediate
proxy may be remembering that a previous upload of 'atsc.pdf' returned 
"The page cannot be displayed" and so it's returning that immediately
rather than attempting the resubmit.

You might also make sure the problem isn't with large files themselves; 
in addition to PmWiki's $UploadMaxSize (which should be set in 
local/config.php and not upload.php, btw), PHP places a limit on 
uploaded file sizes (usually 8M by default) and many Apache 
installations also place a limit on the size of POST requests (512K is 
the default on Red Hat Linux systems).
