I haven't really kept up with it and I'm not sure anyone from Apple
ever responded. But this problem is affecting a pretty significant
number of users and is NOT related to Xcode. From what I can gather, it
seems to affect G5's more often, but not exclusively. Also, some of the
more sane analysis of the problem seems to point to a software problem
in the OS, not a hardware problem. Some people are speculating that the
10.3.4 update will fix it since it contains changes to some of the core
Oh, and I believe there is also a discussion about this at Arstechnica,
although I haven't looked for it. Luckily, my G5 has only frozen twice
and I *think* both times were related to power surges (even though I
have a UPS/surge protector).

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
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
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
some kind. For a while, I thought it was triggered by being in Xcode
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
ssh to the "frozen" machine. I can run commands including "shutdown -r
I have tried killing processes associated with the logged-in user but
doesn't seem to cure anything. I have also tried setting up for
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
doesn't reveal anything obvious).
There are no messages in any log that appear in any way related.
the last message will be minutes or hours before the freeze and the
message will be when I login from the second machine via ssh.
Is anyone else seeing anything like this? It's really weird.
