Hi, all, I'm using uwsgi as my python web app server, and nginx as a proxy. According to the uwsgi documents, the reload should be graceful. However, when I reload the uwsgi, some nginx errors (connection reset by peer) occur.
I have put a* tiny app in the github for presenting the problem*. The project is in *https://github.com/zejiachen/uwsgi_problem <https://github.com/zejiachen/uwsgi_problem>*. Here is the *uwsgi config*: uwsgi: master: 1 vacuum: 1 virtualenv: /home/projects/uwsgi_app/virtualenv procname-prefix: uwsgi_app_ processes: 6 chdir: /home/projects/uwsgi_app wsgi: tinyapp.app need-app: 1 lazy-apps: 1 disable-logging: true logto2: /home/projects/uwsgi_app/var/log/uwsgi_app.log http-socket: 0.0.0.0:3008 stats: 127.0.0.1:4008 max-fd: 65535 reload-on-rss: 256 log-reopen: true log-slow: 1000 buffer-size: 32768 umask: 027 max-requests: 50000 worker-reload-mercy: 10 listen: 1024 harakiri: 20 When I run *http_load* -p 5 -r 5 -f 25 url.txt, and *kill -HUP pid_of_master*, *errors *occur: http://tinyapp.com: byte count wrong http://tinyapp.com: byte count wrong http://tinyapp.com: byte count wrong http://tinyapp.com: byte count wrong http://tinyapp.com: byte count wrong 25 fetches, 5 max parallel, 1050 bytes, in 5.00763 seconds 42 mean bytes/connection 4.99238 fetches/sec, 209.68 bytes/sec msecs/connect: 1.5476 mean, 2.336 max, 1.011 min msecs/first-response: 99.7971 mean, 835.358 max, 1.607 min 5 bad byte counts HTTP response codes: code 200 -- 20 code 502 -- 5 Here is the *nginx error log*: 2015/11/16 09:35:32 [error] 12232#0: *3687 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 127.0.0.1, server: tinyapp.com, request: "GET / HTTP/1.0", upstream: " http://127.0.0.1:3008/";, host: "tinyapp.com" 2015/11/16 09:35:32 [error] 12232#0: *3689 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 127.0.0.1, server: tinyapp.com, request: "GET / HTTP/1.0", upstream: " http://127.0.0.1:3008/";, host: "tinyapp.com" 2015/11/16 09:35:32 [error] 12232#0: *3691 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 127.0.0.1, server: tinyapp.com, request: "GET / HTTP/1.0", upstream: " http://127.0.0.1:3008/";, host: "tinyapp.com" 2015/11/16 09:35:32 [error] 12232#0: *3693 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 127.0.0.1, server: tinyapp.com, request: "GET / HTTP/1.0", upstream: " http://127.0.0.1:3008/";, host: "tinyapp.com" 2015/11/16 09:35:32 [error] 12232#0: *3695 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 127.0.0.1, server: tinyapp.com, request: "GET / HTTP/1.0", upstream: " http://127.0.0.1:3008/";, host: "tinyapp.com" I use uwsgi 1.9.21.1. The problem also occurs when I use the latest version of uwsgi. Could anyone help me?
