My system during idle sometimes has high sysload in 2,3 seconds (around 70% sysload) and then come back to normal after that. I see it ... CPU. Because I can reproduce the issue to see it, but only during 3 or 4 minutes, ... Could you help to advise how I can debug in this case?
First place to look would be at what you do to reproduce it. You could always leave 'top' running with a 0.5 or 1 second refresh in a terminal window, point some sort of video camera at the screen, and after you've reproduced it go back and look at the video frame-by-frame until you find the 'top' refresh(es) that happened during the high load.
