Unlikely to be anything you did to the software. Most *ix-like operating systems (including Linux) rely entirely on the hardware being in good condition. If you have faulty hardware, you can get unpredictable problems. The only hardware faults that people have written software around are ECC errors, ethernet faults, disk faults and other common problems. Usually if there is a processor fault it is very difficult to handle in software, so instead of panicing or issuing an error message, the machine simply fails to work properly and can hang. Intel hardware usually runs very slowly when it gets hot; it's a hardware feature to stop the silicon melting itself. Some AMD processors can, too (others just cook themselves). I had some really bizarre faults on my home system last January where it would simply hang, no interrupts, no nuttin'. It turned out that I needed to re-seat the AMD Coppermine processor in its socket. After that, all has been OK. Hope that helps, Jill.

G'day all... I've a Mandrake 8.2 server (2.4 kernel) with iptables. The server has had overheating problems in the past. (Replaced the heatsink/fan unit.) The other day it stopped responding after I'd been adjusting the firewalling rules. I couldn't log into the machine at all and it appeared to be running very slowly. At the time I thought this was more overheating problems. I replaced the server relatively quickly, and I've been diagnosing it. I booted the machine using the installer CD witht the rescue option and renamed rc.firewall so that the scripts it contains wouldn't be run. When I rebooted it, I could log in fine. My question is that could an incorrect firewall (iptables) rule been the cause of the fault? Thanks Mike --- Michael S. E.
