我在我的 uWSGI 日志中得到了以下回溯，我不知道从哪里开始寻找答案：
DAMN ! worker 5 (pid: 29056) died :( trying respawn ...
Respawned uWSGI worker 5 (new pid: 29088)
DAMN ! worker 6 (pid: 29080) died :( trying respawn ...
Respawned uWSGI worker 6 (new pid: 29089)
!!! uWSGI process 29089 got Segmentation Fault !!!

我在 Ubuntu 14.04 LTS 上运行 uWSGI 版本 2.0.9 以及 django 1.7.4 和 nginx 1.6。这是我的 uWSGI 应用程序配置：
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 配置：
worker_processes 8; # 12 cores
worker_rlimit_nofile 100000;
pid /var/run/nginx.pid;
events {
worker_connections 16384;
use epoll;
multi_accept on;
}
...
此外有时还会出现以下错误：

该代码在具有 6 个内核和 ubuntu 12.04 LTS 的机器上运行没有错误...任何想法都很好...谢谢
