Swap: 2048M Total, 201M Used, 1847M Free, 9% Inuse, 27M Out In this line, top reported 27M Out. However, systat -vm only shows 13.5 MB transaction for the same period to the device. We need 3 terminals to observe: term1 % top term2 % systatm -vm 1 term3 % swapon term3 % mount -t tmpfs tmpfs /mnt/tmp term3 % dd if=3D/dev/zero of=3D/mnt/tmp/large.txt bs=3D1M count=3D3000 Also Having 1 swap device makes easier to observe. --=20 You are receiving this mail because: You are the assignee for the bug.=
