I'm relatively new to the CoreOS world, we had a server reboot and the messaging in the Journal is extremely vague:
Sep 18 07:10:27 ip-x-x-x-x.us-west-2.compute.internal kernel: BUG: unable to handle kernel NULL pointer dereference at (null)
-- Reboot --
I was looking at Memory and CPU on this system using some cloud Monitoring that we use, and CPU and Memory were not increasing and everything looked fine.
So biggest question is, how do I go about figuring out what caused this random reboot?
Thanks!
