10.3 was a fairly stable release.
The longest running devices on our network are likely some DECserver 100's
stuck somewhere long since forgotten. Every year or two, we get a phone
call about terminals not working and it turns out the original load host
for the terminal server had been upgraded several times in the last decade,
and eventually retired from service.
There is something to the saying "If it ain't broke, don't fix it."

That's a PPro running Linux. Uptime would be higher if we hadn't
upgraded it.

That was a Linux/Intel dual-ether router -- it finally crashed about 5
weeks later after a major power-failure when the UPS battery ran out.
I agree with the previous comment of "if it ain't broke..." The above
machine was running 1.0x (I think it was .09) kernel even though 2.0 was
out, but it was performing fine as it was (btw, the login shown was the
console session logged in right after boot).

I've had a Linux box run some 540 days...only rebooted because I had to
physically move the system and I didn't want to crash the hard drive.
2 years is impressive though.
