Now just hit 1500 days:

Utterly remarkable - the box gets no maintenance at all.
I would love to know how much data it has delivered, but alas, in 2001 I
wasn't up-to-speed with that sort of thing :-)

Hi Norbert,
Yes, uptime 'wraps' at about 493 days or something.
use:
last -xf /var/run/utmp runlevel
to get last change to run level (run level at boot, presumably). This was
posted on LKML ages ago where I learnt to use it to get true 'uptime'.

1024 load averages? I have never seen anything above 1.5 on any box I run?
You sure?

Impressive indeed. I had a SPARC LX running Red Hat 6.1 or 6.2 I think it
was, stripped down for a web server and I got 585 days out of it before I
had to pull the plug to relocate it. It weathered NIMBDA, an FTP exploit
and numberous other things for nearly 2 years.

You need to change LOAD_FREQ, FSHIFT, and EXP_1, EXP_5, EXP_15 in
<linux/sched.h>.

We got one to 1460 or so, then got BSOD on the controller which switches
from the UPS to the diesel when they get up to speed, dropped power on
the whole data center (at work).
I ran one at home from the night 1.2.13 was released (or two days after
when a patch came out) until the afternoon before Y2K, when I decided I
didn't want to have that system to check at midnight. It was an 8MB
386SX-16 named "glacial" for its performance rather than because it was
cool ;-) But it did DNS nicely, which was all I could ask.
I think you have the record, though.

I'm not sure about that one. =)
I had a Pentium 233MMX pc running for 5 years 3 days. Booted Nov 18th 1999
and was downed due to a UPS failure around Nov 21 2004.
5 years counting 2 leap year days (2000 and 2004), that's 1827 IIRC.
It was running kernel 2.2.13, 64mb ram, 1.6gb disk, it was a dns server nfs
root server and a NIS server. Other than that it didn't do much. It did
get use via the network everyday. Too bad I don't have a last entry from
utmp before it was killed.
If anyone is interested in the last entry, I'll see if I can dig itup from
old backups.

No, I wasn't even thinking that - just reporting what a wonderful job it all
is - and yes, power supply here in Pompey UK is good (but we do pay thru' the
nose for everything in the UK). The last time I _did_ reboot that machine
was when my kettle lead shorted out and blew the fuses to my flats 240v
supply ring main.
According to the Linux counter site, there are more higher (my machine is 3rd
in the list):

I tried to run their scripts on my system, but being as old as it was
(debian hamm I believe), I think I had problems. Either that or it was
before they knew about the "last -x ..." thing.
I just looked, Dang, I could have had the record by over 100 days. Oh
well, maybe my alpha might:
18:03:07 up 902 days, 1:12, 6 users, load average: 0.00, 0.00, 0.00

I submitted the 'last -x' patch to them - I think it is in the beta scripts
now. I run the 'last -x..' version on the 486 and my gentoo box as I had to
test it all worked ;-) I dunno how the other boxes do it > 493 (or whatever
it is)

It's a good site, with a lot of work... been there a long time too. Some of
them kernels I never heard off though.

There is an interesting point here that is worth noting. I don't think I
would BEGIN to try this with a 2.6 based kernel. And I am not sure it is
doable yet with a 2.4 kernel if the machine is to be exposed to the wild.

497 days. (2^32 / 8640000 days IIRC)

it may depend on what you do with it. I reached 1000 days with a
2.4.19pre5 plus a lot of patches a few years ago. However, it would
have been dangerous to leave this machine exposed because there were
so many local root exploits that the smallest vulnerability in any
installed service would have cause a disaster. But I also have some
machines running 2.4.22+some patches which have not been rebooted
since kernel upgrade, and which are used as front firewalls on a
big fat internet pipe, and they are still up and running normally.
So I can say that 2.4 was stable enough 2 years ago, and is even
more right now. Judging from the many people reporting years of
uptime (and from local experience), it seems that 2.4 reached such
a stability around 2.4.18.

And the old GE/Honeywell 600 crashed due to rollover at 35 days, and we
hit the bug first three years after it was coded. Hardware is better!
