spi-tools and spi-tools-dev both occasionally get wedged. HTTP requests just hang and eventually time out with a 50x. Nothing gets logged in either my django application log, or in uwsgi.log. If I restart the service, things are fine until it happens again.
Any ideas how I can get better visibility into what's happening? Can I make uwsgi do more verbose logging? Is there any way I can see the request progress through higher levels of the stack (nginx, etc) so I know where things go wrong?
