Twisted server crashes unexpectedly while running django
There is no 499 http code in rfc. Nginx defines 499 code itself.
When a client sent a request, and closed the connection without waiting forthe response, a 499 code occurs. If there're a lot of 499s in youraccess_log, it's mostly caused by the slow back-ends (too slow for yourusers to wait). You may have to optimize your website performance.
- you say the problem is from a client hitting a particular url (reproducible?)
- since it works for you with gunicorn but not django-on-twisted, either the script is not working properly or
twisted.web2is the issue.
please try $ sh init.sh yourdjangoproject stand.
you can also try to modify run.py to catch SystemExit:
import pdbtry: # __main__ stuff here.except (KeyboardInterrupt, SystemExit): pdb.set_trace()
