nginx+fastcgi出现worker process 1297 exited on signal 11

    各位大神，请帮小弟看看下面的问题：
我使用Nginx服务器+fastcgi，运行cgi程序，nginx一直提示：worker process 1297 exited on signal 11
使用gdb跟踪，发现如下：
(gdb) c
Continuing.

Program received signal SIGSEGV, Segmentation fault.

如果不调用cgi程序而运行html程序，则一切正常，下面是我的nginx.conf文件：

                }

# proxy the CGI scripts to Nginx listening on 127.0.0.1:9000
#
                location ~ .*\.cgi$ {

                        gzip off; 
                        fastcgi_pass 127.0.0.1:9000;
                        fastcgi_index index.cgi;
                        include fastcgi.conf;
                }
        }
}

下面是启动fastcgi命令：
/var/nginx/bin/spawn-fcgi -f /var/nginx/sbin/fcgiwrap -a 127.0.0.1 -p 9000 -F 2 -P /tmp/fastcgi-c.pid -u nobody -g nobody

请各位大神帮忙分析下，谢谢了

2 个解决方案

#1

SIGSEGV

are u sure your cgi script is bug free?

#2

index.cgi内容如下：
#!/bin/sh
echo Content-type: text/html
echo ""
echo Hello, world.
