[Django]-Troubleshooting Site Slowness on a Nginx + Gunicorn + Django Stack
2👍
We have the same issue on freshly installed system with Apache 2.4 on Cent OS 64 bits. Apache drops connections some time, it was behind nginx, so we get 502 Gateway error very often. There were nothing in logs, nothing with enabled debug, no crash dumps and so on.
The only solution that fixes the problem – rebuild/reinstall Apache completely. We’ve found this solution when added debug output code to Apache sources and rebuild, wondering how our debug code fixes the problem. But it was just re-build.
P.S. Also carefully follow this recommendations on debug WSGI http://modwsgi.readthedocs.io/en/develop/user-guides/debugging-techniques.html
