[GitHub] [apisix] liuning89757 opened a new issue #6704: help request: Is it possible to add another listen port without breaking the existing long-running connections？
liuning89757 opened a new issue #6704:
URL: https://github.com/apache/apisix/issues/6704
### Description
I would like to use Apisix as a loadbalancer, but find out Admin API not provide a function to add a listen port dynamic, so i have to modify Apisix config file like:
```
apisix:
stream_proxy: # TCP/UDP proxy
tcp: # add another TCP proxy address list
- 9100
```
It works out but after execute `apisix reload`, the long-runing connection will be killed because `worker_shutdown_timeout 240s;` is set in nginx.conf. So i suppose to know is there another approach to dynamic add listening port without effect already existing connections？Or is it technical possible to dynamic add port just like add a route using Admin API？
### Environment
- APISIX version (run `apisix version`): 2.12.1
- Operating system (run `uname -a`): centos 7.6
- OpenResty / Nginx version (run `openresty -V` or `nginx -V`): 1.19.9.1

Alright, according to https://github.com/openresty/openresty/issues/644 , maybe it is not possible.

Right, currently, you have to restart the APISIX service, and old worker processes will quit ultimately, for long-running connections, will be closed after the `worker_shutdown_timeout`.
