我在我的uWSGI日志中获得了以下回溯，我不知道从哪里开始寻找解决办法：

module=project.wsgi:application socket=127.0.0.1:7001 pidfile=/tmp/project-master.pid master=True vacuum=True enable-threads=True disable-logging=True #limit-as=4096 # can cause problems with some application (especially on 64bit)? max-requests=8192 processes=12 listen=12000 idle = 3600 stats=127.0.0.1:1717 memory-report = True
这是nginx的conf：
worker_processes 8; # 12 cores worker_rlimit_nofile 100000; pid /var/run/nginx.pid; events { worker_connections 16384; use epoll; multi_accept on; } ...
另外有时会出现以下错误：

这个代码运行没有错误的6核心和Ubuntu的12.04 LTS的机器…任何想法将是伟大的…谢谢
