That got my attention. I think something is broken here and you are into swap but the reporting is quite wrong. I have 192 MB in my laptop running 2.4.9-ac15 w/preemption patch turned on. I fired up a couple Mozilla windows, a couple Netscape windows, Staroffice, a couple acroread windows, a couple emacs windows, Abiword, and I forget what all. Still no swap usage reported. I fired up a second X session and my computer came to a crawl as it tried to run all those apps again. The disk was grinding away--it felt just like a swapping death and yet xosview and top both reported 0 swap usage. I don't believe it was so. I killed most everything, and now the computer feels like it is back to normal, but xosview thinks the CPU is pinned at 100% SYS when nothing is going on. I drag a window around and I get plenty of USR and even some FREE, but let go and it goes back to 100%. Something is broken here, me thinks. -kb, the Kent who might go back to 2.4.9-ac12 later today and ry it again.
