nginx worker signal 11 问题

[imjustfly]

按照如下配置时，配置问题test通过，运行起来的时候，worker不停的退出，信号11，是经典的segmentation fault，应该是内存引用的问题，确定consul地址是正确的：

upstream consul {
    # fake server otherwise ngx_http_upstream will report error when startup
    server 127.0.0.1:11111;

    # all backend server will pull from consul when startup and will delete fake server

    upsync 127.0.0.1:8500/v1/kv/upstreams/test upsync_timeout=6m upsync_interval=500ms upsync_type=consul strong_dependency=off;
    upsync_dump_path /data/server/nginx_consul/conf/upstreams/upstream_consul.conf;
}

server {
    listen 18080;

    location = / {
        proxy_pass http://consul;
    }

    location = /upstream_show {
        upstream_show;
    }
}

woker不停退出的日志如下：

2016/01/06 14:45:45 [alert] 22928#0: worker process 29593 exited on signal 11
2016/01/06 14:45:45 [alert] 22928#0: worker process 29594 exited on signal 11
2016/01/06 14:45:45 [alert] 22928#0: worker process 29595 exited on signal 11
2016/01/06 14:45:45 [alert] 22928#0: worker process 29596 exited on signal 11
2016/01/06 14:45:45 [alert] 22928#0: worker process 29597 exited on signal 11
2016/01/06 14:45:45 [alert] 22928#0: worker process 29599 exited on signal 11
2016/01/06 14:45:45 [alert] 22928#0: worker process 29600 exited on signal 11

每秒几十条，去掉upsync和upsync_dump_path配置项后 worker是可以稳定存活

hi, 按照你的配置测试了一下，没有复现你所说的问题，如下图：

可以在全局加个配置项：
worker_rlimit_core 500M;
working_directory /tmp;
把生成的core 信息发一下，多谢了！

本模块是基于nginx-1.8.0 开发，向上兼容，对于低版本的不兼容。

谢谢！

core文件：

@imjustfly 能提供下完整的配置文件吗？另外问下127.0.0.1:11111是否有服务？
谢谢

[imjustfly]

127.0.0.1:11111没有服务：

$ telnet 127.0.0.1 11111
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused 

这是一个测试nginx实例，完整配置文件如下：

conf/nginx.conf

#user  nobody;
worker_processes  1;

error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;
    include vhosts/*.conf;
}

conf/vhosts/consul.conf

upstream consul {
    # fake server otherwise ngx_http_upstream will report error when startup
    server 127.0.0.1:11111;

    # all backend server will pull from consul when startup and will delete fake server
    upsync 127.0.0.1:8500/v1/kv/upstreams/test upsync_timeout=6m upsync_interval=500ms upsync_type=consul strong_dependency=off;
    upsync_dump_path /data/server/nginx_consul/conf/upstreams/upstream_consul.conf;
}

server {
    listen 18080;

    location = / {
        proxy_pass http://consul;
    }

    location = /upstream_show {
        upstream_show;
    }
}

conf/vhosts/ 目录下只有consul.conf 一个文件

may more detail...

1. 系统环境：内核版本
2. nginx 版本
3. ./configure 后面参数列表

感谢！

[imjustfly]

系统是centos6

$ uname -a
Linux user-6-151 2.6.32-431.5.1.el6.x86_64 #1 SMP Wed Feb 12 00:41:43 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

nginx版本如下

$ sbin/nginx -V
nginx version: nginx/1.9.9
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-4) (GCC)
configure arguments: --add-module=/data/install/nginx-upsync-module-master --prefix=/data/server/nginx_consul/

[imjustfly]

确认在nginx 1.8.0 版本上不会出现这个问题

[xiaokai-wang]

兼容 1.8.+ and 1.9.+
