I am really confusing. I've tried to start node server and after executing lsof -i:5000 I have the following.

enter image description here

That point on same PID and kill -9 1043 don't work. Pls help

CodePudding user response：

The same process listens on ipv4 and ipv6 interfaces (same port 5000). It is ok.

Either it is restarted each time you kill it (PID will change in this case), or you don't have permissions to kill processes of the user (should get "Operation not permitted")
