    What is the longest uptime of your server before required a reboot?

    I have heard or read that one Linux server had an uptime of some 2000+ days before it was rebooted.

    What is the longest uptime for your servers before a reboot was required? And what applications/servers was/is running on the servers?

    I'm curious mostly because I want to learn what Linux is capable of and I wanna be amazed by Linux.

    My server has only been running for

    Howdy,

    I have twice had web/email servers that ran for just a tad over four years with no maintenance, no updates and no downtime. In both cases, the power supplies eventually failed.

    So that goes all the way back to 2004. Don't fix it if it ain't broke...

    So far, the longest time is 2 years (and still running).
    I use KSplice with it so it never needs restarting.

    Thought, I might need to break the trend soon because of Debian 7...

    This is a crappy acer laptop.

    I've had a whitebox 1 GHz celeron with 512MB running Dapper Drake Desktop 6.06 continuously since 2006. It's currently down for cleaning which I do once a year. It really needs it. I have an UPS on it that I've replaced the batteries twice now. The UPS is more problematic than Ubuntu! http://ubuntuforums.org/showthread.p...ight=uprecords

    I typically do my updates once every 6 months, which normally require a reboot, since most of the security patches seem to affect the kernel.

    Re: What is the longest uptime of your server before required a reboot?

    I've been thinking along these lines... Prolonged uptime, I go through power supplies after about 2-3 years, like mentioned above. They would last longer if I blew them out better. I used to just go up and stay up. Now rethinking that strategy for pre-emptive maintenance and diagnostics before a breakdown occurs.

    I've been playing with clusters and server pools... I'm thinking that providing the server "service" in a way that the service is up, without it depending on a single server makes more sense to me... That way the service is still available when things happen or need to be done.

    You can also set temperature alarms, disk alarms, as well as UPS alarms to alert you of problems. And with a 24/7 machine, you will get notices from all of your alarms at the most annoying times. I once got a wakeup call at 4:30 am from my UPS on Christmas morning when I was out of town. A Holiday drunk hit a power pole in my neighborhood knocking out power. My UPS held up for a few minutes just long enough to send emails and text messages. I thought my house was burning down--and there was nothing I could do about it. So if you set alarms, remember that they will annoy you.

    Re: What is the longest uptime of your server before required a reboot?

    I avoid maintaining long uptimes. I need to make sure kernel/service updates don't introduce an error which might cause problems in the case of a reboot. For this reason I schedule regular reboots when I set aside time to make sure the system comes back up. Or, if the system doesn't come back up, my schedule is clear so I can focus on dealing with that one problem. I'd rather keep things running smoothly than have a long uptime.

    The longest a machine has stayed up that I happened to be working on was around one year. I think that was a Red Hat box.
