I would try to find out where the log message above has been generated and ensure it does not only log the information above but also the associated traceback. I assume that the log comes from some framework -- maybe "uwsgi" or "gevent". It is a weakness to log exceptions without the associated traceback. > There is no additional information provided, just that.
