and when i change uwsgi to gunicorn, my app is working well!

[unbit]

please report uwsgi version and your configuration

[mingshi]

at the firest, i use uWSGI 2.0.1 (64bit), then i changed to uWSGI 1.9.2 , but the error continued

the follw is my configuration:

./ run app /tmp/uwsgi.sock 8 uwsgi.log

[unbit]

i do not see enable-threads and as you are using multiple processes you should think about when to call fork()

Check the ThingsToKnow document page for more infos

[mingshi]

i start the app with uwsgi --enanle-threads and i have anthor app also based on flask + uwsgi + nginx, and also used multiple threads, but it worked so well

[unbit]

Sorry but without context is impossibile to help, there are literally dozens of ways for threads in forked environments to crash. Have you checked with --lazy-apps ? it will use fork() like gunicorn. And (for being sure) move enable-threads to the xml file as often i have seen users putting command line options in the Emperor being sure they would have been inherited.

Closing as we do not have enough info to understand
