Linux watchdog tool auto-reboots unresponsive systems

A Linux 'watchdog' tool offers a solution for system administrators dealing with unresponsive Linux machines. This utility actively monitors the system's status and is configured to automatically initiate a reboot sequence when it detects a lock-up or freeze. Implementing this tool can significantly improve system uptime and reduce the manual intervention required to recover from software or hardware-related hangs. The setup process involves configuring the watchdog to effectively identify and respond to critical system failures, ensuring greater operational stability.
