Bug 9741

Recently, I have been seeing my X server die with the following error message:

Backtrace:

Fatal server error:
Caught signal 11.  Server aborting

And then there are several complaints about connection to :0.0 being broken.

I actually saw one of the events just a little while ago.  A screensaver had
just started, and then the X server died.  I suspect the same thing happened
with the other times because they would happen after I had been absent for a while.

I am running this particular server via xinit, I don't know if that affects
anything.  I am also using the open nv driver.  This is on a FC6 machine with a
"nVidia Corporation NV5M64 [RIVA TNT2 Model 64/Model 64 Pro]" video card.

I have seen my X server die like this about three time in the last 3-5 days.  I
have managed to have the presence of mind to save the backtraces for the last
two crashes.

Note: I didn't quite know what to put as the version for X:

euler_1011% rpm -qf /usr/bin/X
xorg-x11-server-Xorg-1.1.1-47.4.fc6

and 1.1.1 is not listed as a valid version option.  However, several of the X
packages seem to have a version number of 7.1, e.g.:

euler_1012% rpm -q xorg-x11-drivers
xorg-x11-drivers-7.1-3

so I am guessing that I have version 7.1 of the software.
