I've got some 2216's that are rebooting. Sometimes they will start chain rebooting, 3-6+ times. Then they will stop. I also went in and disabled the all vlans and re-enabled one by one to see if I could see if it was something going on with one of the VLANs and it then it stopped rebooting. I've had this issue with 7.5, 7.6, and 7.7 now.
Only some of my edge routers do it the chain reboots, but I will see occasional reboots from most of them. I never had any issues with ROS6 and 1072's. The reboots will happen any time of day or night, it doesn't seem to be correlated at all with how much traffic is going through at the time.
I'm running, DHCP, OSPF, PPPOE, NAT, and queues for about 300 customers on this router. Seeing 17% max CPU usage and 1.1Gb usual peak bandwidth usage.
Worth noting is that I had 2 routers both start doing it at the same time last week. I think it might be OSPF related and one of them somehow set off the other or the same thing set off both of them. My head end OSPF router is still a 1072 running ROS6 and doing BGP at the same time. Upgrading that and separating out the OSPF and BGP onto different routers is the next step for me.
