Greetings:
Kswapd on my SLES 8 whipsaws one of my CPU's to 99.9% for prolonged periods of time during high I/O. While this activity is happening, performance and interactive response time goes by way of the swamp.
Can you do a kernel profile and post the results? Boot with profile=1 (before triggering the problem) readprofile -r (afterwards) readprofile -m /boot/System.map | sort -n Also could you test if it goes away when you boot with numa=off ? -Andi
