Many of you have experienced sig-11's, panics, and spontaneous reboots. Conventional wisdom tells us that these problems are caused by bad memory, bad CPU's, overclocked CPU's, and poorly designed or damaged DMA circuitry on the motherboard. I'd been experiencing an increasing number of problems with my server at home. Recently it had failed to stay up for longer than 12 hours. I discovered that the cooling fins in the CPU fan had been clogged with dust. Removing the CPU (with appropriate anti-static measures) and vacuuming out the CPU fan with the narrow vacuum nozzle over the fan and around the CPU fan fins solved my problem. The collection of dust clogged the cooling fins in my CPU fan such that the CPU overheated and the system became extremely unstable. A cheap solution to a potentially expensive problem.
