GDM question

Hi All,


            I have a fedora 7 system running on a dual Xeon CPU X-64


            Everything works ok except for GDM. The GDM application
keeps crashing on the system. It will run for about a week, and then


            This is causing my users to not be able to use the main
screen of the machine, because they cannot get a proper desktop. 


            If they login using freeNX everything works ok.  


            We use this server for running simulations that can take
months to complete (we currently have one that has been running for 9
months) so rebooting once a week is out of the question. 


            Here are the errors from /var/log/messages:


            Feb 18 16:17:36 monet gdm[2964]: The display server has been
shut down about 6 times in the last 90 seconds. It is likely that
something bad is going on.  Waiting for 2 minutes before trying again on
display :0.

            The system is using a Radeon Video card. 


            My xorg.conf file is bellow


# Xorg configuration created by pyxf86config


Section "ServerLayout"

        Identifier     "Default Layout"

        Screen      0  "Screen0" 0 0

        Option      "XkbLayout" "us"

                Viewport   0 0

                Depth     24




Any help would be wonderful.


            Thanks Brent
