Is this the corner case? We can't reproduce this scenario. The webrtc agent should close the udp port after user disconnect. And all processes will exit after MCU stop. Can you please check whether these processes are still there after MCU stop? Zombie processes?

Hi Team,
Process ID and Webrtc ports are not getting released even after ending the call, and this room failure issue is coming, i have ended the process ID and it worked.
Why system is not getting releasing ports and process even after end call or restart MCU
Thanks

Hi, Naresh,
We just logged to your system and did following actions:
1. ./bin/stop-all.sh to stop MCU and all webrtc related processes were terminated
2. ./bin/start-all.sh to start MCU
3. opened connection in chrome and it worked well
4. ./bin/stop-all.sh to stop MCU again and all webrtc related processes were terminated and not related ported were occupied with following command:
ps aux | grep woogeen
netstat -pan | grep woogeen
we'd like to double confirm with your actions, how do you stop MCU? using "kill -9 xxx" to terminate MCU process will not terminate sub-processes, if you want to terminate MCU not using ./bin/stop-all.sh, please try "kill xxx" or "killall node"

Hi Qiujiao,
Do not stop services or ./bin/stop-all.sh i would like you start the services and check netstat -pan | grep woogeen please take a screenshot of it and now and go to the chrome browser and open the basic example app which i have shared you in email, open in multiple tabs or multiple machines refresh multiple times now check netstat -pan | grep woogeen and check the listening ports and pid
now close all the browsers and check again netstat -pan | grep woogeen on server there are several listening ports and pid still active after closing all basic apps also
as you mentioned stopping services and all the ports and pid getting release theres no issue with that
Thanks

We are also facing this issue.
After all sessions ended and disconnected, in the netstat output the woogeen_webrtc keeps the port on status LISTEN.
We are running version 3.5.1
