bug report: 健康检查的时候rise计数不增长导致后端服务器无法上线

2

nginx -t start或者当后端服务器重新上线时，rise计数增长不会超过 nginx 设置的 worker 数量，导致健康检查无法通过 nginx 1.16.0+

这个健康检查实际作用是什么

1

只是一个健康检查吗，仅仅看upstream内的server是否正常吗? 添加了这个模块有看error日志有健康检查的处理，但是没有看到有把down的server踢出upstream

该模块是不是不支持stream里面的tcp健康检测？

我使用的是Nginx 1.14版本，打了check_1.14.0+.patch这个patch，编译也没问题，但在stream配置里面按照类似下面的配置做测试的时候，nginx启动的会提示 nginx: [emerg] "check" directive is not allowed here in /usr/local/nginx/conf/tcp_proxy.conf 如果check放在http配置项里面又不会报错，是我的配置有问题吗，还是本身就不支持？ stream { upstream cluster { # simple round-robin server 10.2.100.101:10001; server 10.2.100.101:10002; check interval=3000 rise=2 fall=5 timeout=1000...

单进程模式会崩溃

1

代码中不是worker进程，不会执行add timers，但是add timers里面执行了一部分共享内存操作，导致后面有访问共享内存的的行为就会崩溃 ``` C if (ngx_process != NGX_PROCESS_WORKER) { return NGX_OK; } ```
