The kernel errata that was made available by Red Hat on August 6 2008 fixes the RHEL4.7 kernel problem mentioned in my last entry.
We have issued a corresponding OE4.7 kernel errata, even though we already had the fix in the stock OEL4.7 kernel. You do not need to install this latest errata to fix the problem. You can get the details here:

The Corresponding Red Hat bugzillas are:
RH bug 455525
RH bug 455074
RH bug 453507
Explanation of the changes (quoting from the Red Hat errata text):
"A set of patches detailed as "sys_times: Fix system unresponsiveness
during many concurrent invocation of sys_times()" and "Minor code cleanup
to sys_times() call" introduced regression which caused a kernel panic
under high load. These patches were reverted in the current release. "
