Two questions about uwsgi:
*(1) Server one: *I have installed nginx+uwsgi using the script on a test
server. web2py works fine, but the uwsgi.log file shows a new entry every
second (marked red).
And there is a warning (green) - how can I run uWSGI not as root?
This is the logfile after a restart (sorry, I know, there are many lines):

*(2) Server two* (for the production): it should be the same installation,
but now the uwsgi.log file contains:

I have spent some hours, but I could not find a solution.
Who can give me a hint?
