Do I remember this is 5.7? Look at the announcement that *just* came out
in the last hour, with the libX11 bugfix.
<https://rhn.redhat.com/errata/RHBA-2011-1351.html> says "Previously, in
the 64-bit mode, libX11 computed addresses using the 32-bit arithmetic. As
a consequence, under heavy load, applications running in the X environment
terminated unexpectedly. A patch has been provided to address this issue,
and the crashes no longer occur in the described scenario."
