site_archiver@lists.apple.com Delivered-To: darwin-dev@lists.apple.com Hello all, launchd tries to restart indefinitely some service in the following two cases: 1) launchd plist with wrong ProgramArguments key " Throttling respawn: Will start in 10 seconds posix_spawnp("<ProgramArguments>", ...): No such file or directory " The problem is very annoying if some other application waits for this service to start. 2) a service keeps crashing CrashReporter never shows even if I have the CrashReporterPrefs on "Developer" level. It is true that it says: "Display the Unexpectedly Quit dialog for all the processes run by the user". Mac OS X 10.4 had a limit (LAUNCHD_FAILED_EXITS_THRESHOLD). What was the reason to remove it ? -- Terry _______________________________________________ Do not post admin requests to the list. They will be ignored.

You might argue for a cascade failure, where if service A won't load, B should fail in its attempt to contact A rather than launchd answering the phone and being unable to hand off the connection to A. On the other hand, you could argue that while what it's trying to launch doesn't currently exist, it will in the future as a result of a not yet completed operation (a network mount, a disk mount for a disk currently being fsck'ed, a thumb drive containing your ssh keys being inserted, or the binary is in fact being generated, etc.). You could also argue that "the plist needs fixed" and/or "do not install busted plists in the first place". Since there's no way to distinguish a transient vs. Permanent failure, and you presumably intentionally installed it, you intended launchd to keep trying. Is this the system launchd, or the per-session launchd? You will only get the dialog if it's something that's in the current GUI context (search for "CrashReporter" on <http://developer.apple.com> for more details). You could as Dave or file a bug. But see above; there are legitimate reasons for persistently retrying. Probably they outweighed the likelihood of an actually broken plists remaining installed or exporting a service legitimately required by some other process and the system remaining functional.
