Darwin-dev mailing list (Darwin-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-dev/site_archiver%40lists.app… I don't think one can explain it any better than the launchd.plist(5) man page (emphasis mine): KeepAlive <boolean or dictionary of stuff> This optional key is used to control whether your job is to be kept con- tinuously running or to let demand and conditions control the invocation. The default is false and therefore only demand will start the job. The value may be set to true to unconditionally keep the job alive. Alterna- tively, a dictionary of conditions may be specified to selectively con- trol whether launchd keeps a job alive or not. If multiple keys are pro- vided, launchd ORs them, thus providing maximum flexibility to the job to refine the logic and stall if necessary. If launchd finds no reason to restart the job, it falls back on demand based invocation. Jobs that exit quickly and frequently when configured to be kept alive will be throttled to converve system resources. SuccessfulExit <boolean> If true, the job will be restarted as long as the program exits and with an exit status of zero. If false, the job will be restarted in the inverse condition. This key implies that "RunAtLoad" is set to true, since the job needs to run at least once before we can get an exit status. I am not sure I understand what you are suggesting here. The important part in my situation with respect to the usage of SuccessfulExit is that RunAtLoad is false. The documentation would seem to indicate that to use SuccessFulExit, RunAtLoad needs to be true. In my situation, changing RunAtLoad to true would not be the correct behavior. The server should only run upon receiving a request from the Client and once the request is completed, it should stop running (well, unless another request has come in). The part which says that "jobs that exit quickly and frequently will be throttled" shouldn't be what my situation entails for this sample code. It might exit quickly, but there should be only a single invocation of the server and it should just stop running. This email sent to site_archiver(a)lists.apple.com

As far as I can tell, your server currently quits immediately; this is interpreted by launchd as a failure that occurred while launching the daemon (at least, this used to be case). Could you try by inserting a delay of ten seconds or more between your two NSLog() statements? Jul 18 21:45:26 Glamdring server[12831]: Hello, the server is going away ... Jul 18 21:45:27 Glamdring server[12833]: Hello, the server is here... Jul 18 21:45:37 Glamdring server[12833]: Hello, the server is going away ... Jul 18 21:45:37 Glamdring server[12841]: Hello, the server is here... Jul 18 21:45:47 Glamdring server[12841]: Hello, the server is going away ... Jul 18 21:45:47 Glamdring server[12843]: Hello, the server is here... Jul 18 21:45:57 Glamdring server[12843]: Hello, the server is going away ... Jul 18 21:45:57 Glamdring server[12845]: Hello, the server is here... Jul 18 21:46:07 Glamdring server[12845]: Hello, the server is going away ... Jul 18 21:46:07 Glamdring server[12847]: Hello, the server is here... Jul 18 21:46:17 Glamdring server[12847]: Hello, the server is going away ... Jul 18 21:46:17 Glamdring server[12849]: Hello, the server is here... Jul 18 21:46:27 Glamdring server[12849]: Hello, the server is going away ... So, you can see the effect of the call to sleep, but launchd won't let it die. This email sent to site_archiver(a)lists.apple.com
