[GitHub] [apisix] whioue opened a new issue #6540: bug: health check Sometimes there is data, sometimes there is no data
whioue opened a new issue #6540:
URL: https://github.com/apache/apisix/issues/6540
### Issue description
1.当我配置了upstream的主动以及被动健康检查，关联route并成功转发请求后，使用curl频繁访问/v1/healthcheck，发现有时返回数据，有时不返回数据。
2.我还发现使用不同的终端（浏览器和postman）频繁访问/v1/healthcheck，发现postman能获取数据，浏览器却获取不到，如下：
浏览器：
postman:
curl:
### Environment
- apisix version (cmd: `apisix version`):v2.8
- OS (cmd: `uname -a`):centos7
- OpenResty / Nginx version (cmd: `nginx -V` or `openresty -V`):
- etcd version, if have (cmd: run `curl http://127.0.0.1:9090/v1/server_info` to get the info from server-info API):
- apisix-dashboard version, if have:
- the plugin runner version, if the issue is about a plugin runner (cmd: depended on the kind of runner):
- luarocks version, if the issue is about installation (cmd: `luarocks --version`):
### Steps to reproduce
配置大致如下，能获取到后端响应：

}
}
},

Thanks for your valuable reply, I will try to reproduce it.

It seems same with https://github.com/apache/apisix/issues/5953, can you provide more detail of how to reproduce it?

不知您说的更多如何重现它的详细信息指的是什么？没有特殊的配置，正常配置路由，在upstream上开启健康检查，并使用以上我所描述的方式访问就可复现。我当前是部署在18核32G的机器上测试使用，我猜测多worker下运行apisix可能更容易复现，您可以试一下，我认为很容易重现这种情况。

我刚刚再次复现，可以把nginx.conf中的worker_processes设置稍微多一些，然后现象比较明显，应该是有的进程没有参与转发，因此查询健康检查的时候有的worker中没有存储健康检查数据？愚见仅供参考，希望修改此问题，谢谢。
