[MT-AU Public] Mikrotik Reboots

HI all, has anybody else seen a sharp increase in MT devices just rebooting for no reason of late ? In the past month or so we must have had about 10-15 reboots for no reason. We have seen a mix of OS versions doing it, even ones with the latest bugfix version on them. CCR's, RB1100AHx2's, Grooves, QRT's, Omnitiks, they just seem to be rebooting out of the blue, it's really strange. We run a lot of MT gear and we are seriously seeing a couple a week just reboot for no reason and I am getting a bit concerned about it. They are all rebooting due to watchdog failure, just the default OS one. I'm interested to see if anybody else is experiencing the same. Regards Paul
