Random X crashes on FC 1

[Ben Sheron]

Hello List

I am having a problem with XFree86 crashing in a seemingly random manner
and then restarting, thus logging me out.  I found the following in
/var/log/messages:

Jan 24 11:57:33 leartes gdm[2356]: gdm_slave_xioerror_handler: Fatal X
error - Restarting :0

I'm not exactly sure what causes this, but it tends to happen if I leave
a program running while logged in for a long time (around 3 or 4
hours).  Any ideas as to what this is caused by?

In case any of you are wondering why I have not upgraded to FC 3, it is
because I use this box for audio work, and use the PlanetCCRMA package
for FC 1.  The 2.4 kernels are better for low latency than 2.6 at this
point (so I'm told; correct me if I'm wrong), so I stick with FC 1 to
use 2.4.

Thanks for any help.

Ben
