However, in Linux land, this is not typically necessary as a 'rule'. You could certainly be running applications with memory leaks or other special circumstances that warrant a clean boot. I have several Linux boxes running a variety of flavors including CentOS, Debian, and even Redhat (think old 8.x/9.x days) with uptimes ranging between 13 months to over two years. They're running perfectly without the 'yearly reboot'. --Tim
