Hellishly long strace of the X process during the hang
What video card are you using? Please attach your X server log and config file as individual uncompressed file attachments, as well as /var/log/messages from the last boot onward. Thanks in advance. Nvidia Quadro 4 980 XGL We still require the files requested in comment #2 above in in order to do further troubleshooting. Once you've attached all 3 of the the requested files, we will review them and resume troubleshooting. Thanks in advance. Setting status back to "NEEDINFO" pending requested files. This system got rebooted so the Xorg.0.log got cleared. I'm going to attach the X config file, and I'll post the other two files when the problem reoccurs. I've also noticed that this machine is configured to use the propriatary nvidia driver, so it might be in their code. Created attachment 107642 [details]
X configuration file for system in question
Since this X.org version was released,, there have been several
major updates to the X Window System, which may resolve this
issue, assuming it is an X.Org issue. Users who have experienced
this problem are encouraged to upgrade to the latest version of
Fedora Core 3, which can be obtained from:
http://fedora.redhat.com/download
If this issue turns out to still be reproduceable in the latest
version of Fedora Core, please file a bug report in the X.Org
bugzilla located at http://bugs.freedesktop.org in the "xorg"
component.
Once you've filed your bug report to X.Org, if you paste the new
bug URL here, Red Hat will continue to track the issue in the
centralized X.Org bug tracker, and will review any bug fixes that
become available for consideration in future updates.

Users will encounter a condition where the X server is completely frozen. There doesn't appear to be any pattern to usage or behavior, but the results are the same. The X system is frozen, but the machine is up and can be accessed via the network. Top shows that the X server is at 100% CPU utilization and an strace produces the following output. gettimeofday({1101235459, 967733}, NULL) = 0 gettimeofday({1101235459, 967837}, NULL) = 0 gettimeofday({1101235459, 967962}, NULL) = 0 --- SIGIO (I/O possible) @ 0 (0) --- select(17, [15 16], NULL, NULL, {0, 0}) = 1 (in [16], left {0, 0}) rt_sigprocmask(SIG_BLOCK, [IO], [IO], 8) = 0 read(16, "8\365\374\0", 64) = 4 gettimeofday({1101235459, 968835}, NULL) = 0 rt_sigprocmask(SIG_BLOCK, [], [IO], 8) = 0 select(1024, [16], NULL, NULL, {0, 0}) = 0 (Timeout) sigreturn() = ?
