upload_max_size is not the only variable that would affect uploading.
You may also want to look at the settings for:

post_max_size -- uploading files is done through the HTTP POST
mechanism so this has to be at least as big as upload_max_size
memory_limit -- If memory limits are enabled, this also must be larger
then upload_max_size

It may also be a 32bit limit as well:

(from php.net)
Note: PHP allows shortcuts for bit values, including K (kilo), M
(mega) and G (giga). PHP will do the conversions automatically if you
use any of these. Be careful not to exceed the 32 bit signed integer
limit (if you're using 32bit versions) as it will cause your script to
fail.
