[Observium] uptime issue ?

Hi,

we are using 0.16.5.7901 (Stable) and have got some wrong alert of rebooting devices after 1 year, 132 days, 2h, 23m Actually they didn't reboot but uptime graphs restarted. Can be a kind of counter overflow ?

Affected devices are some brocade san switches and juniper isg1000

Regards, imedve
