That's really scary, man. What if the system tries to reboot and crashes on the way back up? It's happened to me before. Go reboot that damn thing!

- ygra 13y agoSo that it crashes now? ;-)
- eru 13y agoThat'll crash it when he has the time to look into it, and has backup handy. Not at a random time.
- excitom 13y agoThe last time it rebooted was due to a power glitch at the data center. Came back up just fine. Prior to that, uptime was over 1,000 days :-)
- Amadou 13y agoYou don't understand his point. He's saying, how do you know that the system hasn't acquired some sort of configuration/software/hardware degradation in the meantime that only manifests on boot? If you don't regularly exercise/test a critical function, then you substantially increase your risk that the critical function will fail when you really do need it. Q: What's the worst time to find out your system won't boot? A: Right after it crashed. You are better off with scheduled maintenance periods where you can reboot the server and it isn't critical if it fails. That gives you a chance to correct anything on your terms rather than fire-fighting.
