Stopping node.js process on Mac

Question

I have a node.js application that uses some socket ports. Sometimes, when I exit the application with Ctrl + C, some kind of node process is left running, still allocating the socket ports. Thus, I cannot restart my application, since it fails to open those ports. When I look the situation with ps, I get the following response:

$ ps

PID TTY           TIME CMD

40454 ttys000    0:00.11 -bash

41643 ttys001    0:00.00 (node)

41741 ttys001    0:00.00 (node)

Trying kill -9 41643 doesn't kill the process. Is it a some kind of unkillable zombie? How can I get rid of those (node)-things blocking my tcp ports?

Answer 1

I'm not a MAC user, but here is what I use to kill all the available node processes (under linux):

sudo killall -9 node

Answer 2

On macOS, it's simply:

sudo killall -9 node

For a lot of the times, sudo is overkill, but in your case, it looks like you might want to try sudo.
