Re: Another lock up
:I was in X. All of a sudden I lost input focus, windows of my aterms in
:Window Maker changed colour when moving focus, but I couldn't type anything
:I noticed the disk thrashing like crazy. Every once in a while I could
:close some aterms and switch workspaces and close others.
:Some dockapps were also whacked in that their static image was showing and
:where normally dynamic images are were whited out.
:After a while it even stopped reacting to the switching of the workspaces or
:closing of the aterms. So I pressed ctrl-alt-bs, this worked to create one
:screen, no aterms, and a mouse pointer. However, I couldn't use the mouse
:pointer any more, didn't drop to console, couldn't forcefully drop to
:console. After the diskthrashing stopped I tried to go to DDB, also didn't
:Had to power off and on.
:This box is on 256 MB and uses swap quite often. Personally I am inclined
:to say that it is triggering something in the VM system along with IO.
:However, I am totally at a loss at what it could be, since I am unable to do
:anything about it to gain more information.
:I did enable console.log and all.log in case something MIGHT be printed on
:console and thus I am able to capture it.

It definitely sounds like a thrash related issue... actually, it kinda
sounds like the X server might have been killed or something. I'm hoping
that it's that and not an actual system freeze.
What I suggest is that when the situation starts to happen, ctl-alt-Fn
out of X and into a console, login as root, and see if you can determine
what the cause of the thrashing that way.
You could also try nice'ing down all X-related programs. If that actually
works then we *know* it's a scheduling issue.
We know that there are definitely scheduler issues... I think I blew it
somewhere in the last month and it is not scheduling cpu-bound programs
