I've found the problem: the view rendered by the function has an {{include
'otherview.html'}} and that otherview.html had an error.
What is strange is that web2py never throwed 500 error :/
In my laptop I have the exact same configuration as in the server (that is,
nginx, uwsgi, same web2py version, same routes.py), and here in my laptop
it does throw the 500 error. Don't know why in the server hangs until
timeout.
