Thanks for responding Justin, I think I have it working now, The KEXT disconnected from it before, but after 250 connections it still started that mess, but now In the daemon I have it creating a socket then accepting and after it has done the communication, I close the the socket and it is working fine now.

Another problem has come up that I can't find addressed in Steven's book. I have a daemon running forever accepting connections and then receiving info and responding back to my KEXt all using the AF_UNIX sockets, This works great except when the daemon has received about 250 connections it starts throwing error 24 (EMFILE) too many files open, I know that a process's limit of this can be increased, but I would like a fix that doesn't require that, I want it where after the connection was accepted by the daemon and it receives and sends info, that it can close that connection, so as to prevent this error. Hmmm...it sounds as if you haven't completely figured out your communication scheme. First, if this is communication between one daemon and one KEXT, why keep opening connections? Can't you reuse the same one? Second, if it is important to have new connections, why can't one end or the other close when done? The last guy to send can cloes his end; and the last guy to receive can close the socket, at which point the whole connection goes away. Perhaps I don't understand enough of what you are trying to achieve. Regards, Justin -- Justin C.
