Let me guess, you use session_start() near the top of every page (maybe
through a include auto_prepended).
This has bitten me before, if you do that, other requests to open that
session file will block until the other request closes the session file
(i.e. at the end of your download script).
You could force the session finished/closed before doing any
long/non-interactive tasks. This releases the lock on the session file
for that session ID.
Cheers,
Andy
