Best way to make a system ROCK SOLID
I work on a system that will serve in an industrial environment. This is an industrial PC running Red Hat 9.0. No alternatives for the distro, I need some drivers that were pre-compiled for Red Hat 9.0.
Does any of you got tips to make this system very - very - stable? And to prevent system freezes that need a hard reboot? That would be critical since the places where the system is to be installed are quite remote.
The system simply runs a X server (no window manager) and a graphical application over it. It communicates on a few serial ports and a modem and it's sometimes networked by Ethernet.
Any opinions will be appriciated.
