VegaStream has some very nice ATAs and T38 devices (still), but after the upgrade to VEGA400_R082S017 (8.2.17) every two and a half day their system.sysUptime counter gets resetted:
> Host : sjh-vega400 > Output: Uptime is less than an hour! (328.61 seconds) > Date : 2008-02-28 14:21:08
According to Nagios, this happens every two and a half days:
The device doesn't reboot, the sysUpTime count just goes back to zero. Device itself says it's up for 9 days.
About 2 days, 11 hours, 37 minutes, 62 seconds.
214682 seconds...
0x3469a...
Update
Thanks to callum on irc.oz.org/#bugs : 2 ^ 31 / 10,000, or an
overflow of the signed counter of the number of 100 microseconds.

This device measures... 2RU by 19 inch by (grabs measure-tape) 40 centimeters.

The number 36: When talking about health it's a good number: 36 degrees Celcius is good. When talking about a pregnant woman it's a good number: 36 weeks is still a month to go!
And for both situations, everything above 40 is bad.

If you're coding, interesting numbers will show up sometimes!
49 days = 49 days * 24 hours per day * 60 minutes per hour * 60 seconds per minute * 1000 ms = 4,233,600,000, or 0xFC579C00, or close to 0xFFFFFFFF. In other words, some unsigned 64 bit millisecond counter just overflowed.
Same story here, except that is an signed 64 bit millisecond counter.

| 86400 | Number of seconds per day |
