I'm running 5.4R on a dual Xeon machine. Until today all has been fine, system is usually 80-90% idle with a load of 0.2-0.3 all the time. Suddenly it's consistently only 40-50% idle with a load of 1.5-2.5. top shows nothing except that the load is coming as system processes, 30-40% where it used to be only 2-3%. However, running top with -S still shows nothing.
I don't recall doing anything that would explain this. What can I look for to explain this sudden increase in system load? I've included a snapshot of top below
