During provisioning of icinga1001, we have experienced two mysterious reboots.
First noted was 2018-10-02 at 21:47Z
Second noted was 2018-11-19 at 17:55Z
- These reboots have not come with corresponding SEL entries
- Debian Stretch was reinstalled several times between these two reboots
- The logs in syslog append a bunch of nulls ("^@") and then kernel startup logs immediately after
This is our primary alerting host at the moment and we can transition to codfw if there is anything you want to check.
