Hi Juliusz, check your nginx log, it could be a some form of 'attack', where you receive the request but soon the client disconnects. If you get tons of this error the performance will be hurt for sure as you lose precious resources. If its normal for your clients to have a big rate of prematurely closed connections (but this looks strange to me) use this: --logto /dev/null to disable all the I/O on your disks -- Roberto De Ioris http://unbit.it _______________________________________________ uWSGI mailing list [email protected] http://lists.unbit.it/cgi-bin/mailman/listinfo/uwsgi
