axeld mentioned the issue in #12670. Saw it tonight trying to figure out a clean way to restart the debug_server.

This works for the DeskBar, so there is at least some support in Launch Daemon for doing it.

Just for reference, this is what the launch_daemon is doing:

I think it sometimes has problems actually finding the correct messenger which is probably causing the issue. I don't remember exactly, but, that problem should be gone once TRoster functionality is handled by the launch_daemon, so I didn't spend too much time on it.

The problem could probably be relieved easily by checking the return code of the SendMessage() call, and only return on success. But that would also mean that those teams aren't properly shut down.
