This one has 48M and does little more than serve NFS, run X, compiles, and a zillion xterm's, tcsh and ssh sessions. I recompiled the kernel making a "try this if you get the chance" change from John, and the problem has not yet surfaced after a few hours. On the other hand, it hasn't felt like it's slowing down either (yet?), so I don't know if it's hard-up for memory yet. It's too soon to tell for me, I think. The other machines are all 16M, do occasional massive NFS client attacks on the above machine (cvs update over NFS is a killer) and lots of recompiles. The problem seemed to be striking most then for processes that had been paged out, but that was not consistant. named died when the machine had been idle while I was asleep. Cheers, -Peter
