So, I have several RB750GL’s running meta routers, most running 5.2
I went to install a new one and upgraded it to 5.7 and it would randomly reboot a couple times a day.
So I downgraded to 5.6 and had the same thing happened.
Then I downgraded to 5.5 and it seems stable. (read: up more that 1 day)
Just FYI.
After you’ve posted this, I’ve checked my logs and you are right. I have an OpenWRT that runs bind (for better DNS) inside one of my 750GLs. In the past few days the uptime was somewhere between 20 and 24 hours.
This is disturbing as I was hoping only the RB450G had this problem
