Just wondering how long people have crunched for continuously without re-starting their pc workstation?

XP I've gotten a couple of months out of, but it does nothing but crunch.
Vista needs reboot every couple of weeks just because it does.
I've seen a crunching *nix box go for over a year without a reboot.

My old Panasonic Pentium M Laptop crunches at my works and has been on for 6 months or more,
but I don't know if there have been any power failures in that time.Set to auto reboot.

My HTPC runs Windows Vista Ultimate x64 and hasn't been rebooted in over 4 months.

One of my retired crunchers (a 1.8 northwood celeron laptop) would start to develop strange issues after about 30 days, and a reboot would fix it. My main cruncher, I play games and many other tasks on it, so I usually get about 14-21 days on it before I decide to reboot, just for good measure. Usually at that point, there are no strange issues happening, but that's what the reboot prevents.

Linux laptop:
record uptime: 1511d 20h 19m (ended due to the power brick giving-up)

When I was in California 2 of my machines here went almost a year without a restart. They were on the wall and I had to use a screwdriver to restart them, Power outage stopped them.

And no good credit hound!

Just over 6 months so far on an Apple G4 running MB, since last reboot.
However, all it does is crunch Seti.
My overall experience w/ OSX has shown far better stability than -doze, though XP has been good in all fairness.

So many things can influence how long before a re-boot is necessary.
The less hardware connected and the fewer processes being run, the better.
Toss in thermal, dust, and humidity control with a sprinkling of voltage & current regulation ;>)

These are likely more influential to system stability than just the difference in OS.
Though some OS's may be less sensitive & more forgiving than others......

I wager that WIn7 will allow some pretty long "up" times.

I've seen over 3 years continuous crunching for one internal server until it suffered a HDD failure.

Presently 270 days and counting for another machine. A few months for various others until the next security updates or system upgrades.

All on various flavours of Linux.


The main limitation on uptime is due to holiday shutdowns or for when the kernel needs updating!


Much more interesting is for what is the oldest machine still crunching, and for why it is still in service...

Happy crunchin',

I think it might look something like an old server I have at work. I did stop it to upgrade BOINC once.

someone around here has a Linux box that they have a sig showing how long its been running. Last I checked that box was running for nearly 600 days.

This one used to be in top 100 years ago.

Beside real work, it makes almost 2000 RAC.

I think that's me. :p It's not a cruncher though.. it's just the server that runs my entire network. DNS, DHCP, NTP, NIS, IRC, HTTP, FTP, SSH/telnet.

Yeah, it's a laptop and has a battery, but it got put on a UPS somewhere near 400 days simply because it's one of those older laptops that doesn't stop charging the battery, so it will eventually fry and not be able to stay powered on for short outages. I'm pretty sure the HDD will end up failing before I need to power it down for any reason. It was up for about 300 days before the current uptime, and I set something down just slightly too hard on the closed lid and the HDD started clicking right away. Replaced the HDD and started the current run.

I have an HP XW8200 with Fedora11 that is on and crunching SETI@home and rosetta@home all the time. I can usually only go about six months at the longest before rebooting for a kernel upgrade.
