CoreOS 1745.7.0 sudden reboots on k8s worker vms #2475
Container Linux Version
K8s workers without sudden reboots.
K8s workers are rebooting unexpectedly.
If this a kernel panic, pstore may contain some crash logs. See https://coreos.com/os/docs/latest/collecting-crash-logs.html and let us know if there is anything relevant there. I didn't spot anything interesting from your logs above.
Here are crash logs from 2 k8s workers.
In between we upgraded to the new CoreOS stable release 1800.4.0 with the hope that there reboots won't happen, however still the same.
