I have upgrade my server ROS 6.4x to 7.0beta4
It boot loop, I think it's kernel crash.
I have 132 IP Tunnels and 115 EoIP Tunnel in this Server.
So I make a new ROS 7.0beta4 and add tunnels in code , one by one.
when ROS 7.0beta4 have 31 Tunnels add another one,
Now, the ROS restart itself, and boot loop.
sometime, not crash on 32 Tunnels, add to 50 Tunnels, wait for 5 sec, it show again.
