Strange,,,I'm guessing your are at the admin area.
It could mean that php is snooping up memory (maybe another heavy php appl. is using to much of memory resources)
an other option is, standard php is limited (default) in recieving files greater than 8MB.
I don't know if you have root access to your server, but try to modify your php.ini.
Find the line:
memory_limit= 8 (increase this value to for example 16)
and/or
post_max_size= 8 (increase this value to for example 16)
Make sure you'll restart the webserver!
goodluck
