This simple Linux tweak fixes crashes automatically - and it costs me nothing
A Linux software tool called Watchdog can automatically reboot systems that become unresponsive, minimizing downtime without user intervention. It is free to use and relatively easy to install on most Linux distributions, making it accessible even to beginners. While hardware-based watchdogs are more reliable, the software version works on a wide range of systems and is particularly useful for headless servers or remote machines.
