I am using carbon farmework that is not daemon safe and may be due to this I am facing problem. Still, I am confused about one thing. I can start the daemon in 2 different ways, one is using "launchctl load" command and another is rebooting the system. 1. When I use "launchctl load" command, it works fine but if I logout then daemon process first gets the quit event and then it gets killed. 2. When I reboot the system and if I logout it does not get any signals/event to quit/kill. It works fine. I know, Marc has already written about it that In one case your daemon may be connecting to the bootstrap window server service and in the other case connecting to the login session's window server service. System is 10.4.11 ppc. Is it possible to make it work either without removing carbon framework or without splitting in two processes? Please advice me.
