This is usually (it least in all of the cases I have seen/triggered it)
caused by an irrecoverable error on the graphics card. On ATI cards you
will most often (but not always) get a message about missing FIFO space
output to /var/log/system.log. On NVidia cards the problem appears to
be silent.
At this point, the machine is running (in practice it is usually pretty
idle at that point since nothing is drawing) but nothing will ever
reach the screen again.
I also never found a way to recover from this apart from ssh'ing and
sudo reboot (and filing a bug with ATI/NVidia/Apple if it was triggered
by some sequence of calls made in one of our games).
Would be nice to have a way to reset the graphics card via a command
line utility :)

Has anyone else had a problem where the GUI freezes completely?
I'm not 100% sure that it is caused by Xcode but it always seems to
happen
when I'm using Xcode. The problem has been happening on and off since I
upgraded to a Dual Processor 1.8GHz G5 (10.3.3). It has also spanned
Xcode
1.1.1 and 1.2.
Sometimes days can go by between freezes but I think I'm averaging two
freezes per week. The freeze always seems to happen on a window switch
of
some kind. For a while, I thought it was triggered by being in Xcode
and
clicking on a window belonging to another app but today's example was
clicking on Xcode's "find" window from a main Xcode project window.
The freeze only seems to affect the GUI. I can go to another machine
and
ssh to the "frozen" machine. I can run commands including "shutdown -r
now".
I have tried killing processes associated with the logged-in user but
that
doesn't seem to cure anything. I have also tried setting up for
two-machine
debugging but the machine doesn't trip into debug mode unless I hit the
power button on the LCD screen (and then debugging from the second
machine
doesn't reveal anything obvious).
There are no messages in any log that appear in any way related.
Typically,
the last message will be minutes or hours before the freeze and the
next
message will be when I login from the second machine via ssh.
Is anyone else seeing anything like this? It's really weird.
