Which kernel version did you say they're running?
Currently running kernel-2.6.32-220.7.1.el6.x86_64. All RHEL6 systems run builds of kernel version 2.6.32.
Did you try running with "nohz=off"?
I haven't yet. I'll try that, but it was just a guess that it may be related to that, not based on any observations.
