[launchd-dev] UNIX SOCKET problem

Hi, I use a UNIX socket to talk with a deamon. It works fine when I start my deamon listening but when I shutdown the deamon and I restart it I get a listening error: invalid argument... I have to delete the mysocketfile.sock from filesystem and then restart the deamon... then is recreated by the app (deamon) and all is doing fine... note: a) I unlink the socket Address path when I create the socket b) I close the socket when I quit the app... any Idea???? I have to remove the socket file from the filesystem??? thnx + regards Gian Luca
