Hi,
I have question about Uptime counter on RB 1100AHx2 running RouterOS 5.24.
After about two years of running i got reset of Uptime counter that now shown 11 days uptime. There was no reboot of any kind. 
Is this a known issue?
manson, maybe this: Uptime Challenge!
yes, the counter has a limit. this is normal, router will work as usual. if you want to take part in the uptime chalenge, just add 497.1 days to your current value
