I did just about everything I could think of. Hardware reseated, kernel recompiled, took the case off the computer. Whatever it is, it seems to be working. The system is stable. I'm going to wait and see if it remains so. Besides the actual work on the server, the main environmental difference has been the outside temperature. It has been very cool outside for the past two days. This may be giving me a 'cleaner' electrical feed. In any case, I am giving serious consideration to having another 20amp circuit installed to another UPS. Especially if the server tends to die when the outside temperature goes up.
