Why Does a Server Restart Without an Administrator Rebooting It?

11/10/2026

Unexpected restarts can follow a host event, kernel failure, watchdog action, power issue, or automated maintenance.

Checks to make

Compare uptime and boot time with provider event history, kernel logs, monitoring alerts, and scheduled maintenance. Check whether a process or watchdog initiated the restart, and preserve logs before repeated reboots overwrite evidence.

When to get help

Hosting operations can correlate host, kernel, and application evidence. Informatix Systems can assess the symptoms, evidence, and next steps. Contact Informatix Systems to discuss this issue.
