Sql server also (using 4% of the cpu time). Load averages run less than 2.0 at the highest. I'm concerned I have a hardware failure (drive?) coming. Are there any issues with 3.1-S that I am not aware of? Could faulty motherboard / memory cause this kind of errors? We have a dozen or so freebsd boxes, 4 of them are ABit based - these seem to cause us 90% of our problems. Any ideas on where to start would be greatly appreciated.
