Eric,
launchd (if you're on the Tiger) is the way to go. Download Lingon, and use wizard to create the correct job.

I'm writing a Cocoa app that needs to run 24/7, and it's looking pretty decent so far. Still, I'm thinking it would be prudent to have some way of making sure it's always going, and automatically restart it if it fails.

Does anyone have advice on this?

You could schedule a script (with cron or launchd, depending on the OS version) to run every so often to check if it's running and if not, start it with "open".


Although frankly I'm not a big fan of such an approach. Blindly restarting an app without first determining the reason it failed is very rarely a useful thing to do. Quite often it will simply fail again.

Thanks. I'm with you on that. I'd probably do something like send an email with the failure notification as well as relaunch the app, but the app's gotta keep going no matter what.
