uhm, you left out some pretty specific details.... what resources has the 
server web2py is deployed on ? moreover, what's the size of the file ? and 
what code are you using to handle the upload? are you using the default 
'upload' Field or is it in conjunction with a 'blob' one to store the file 
on the database ?
