Hi Jeff, Since I don't have RedHat support, I opened a bug through bugzilla.redhat.com. The bug number is 800082. I see that it was assigned to you. Thank you for future correspondence while troubleshooting this bug. I can coordinate with the end user experiencing this bug, if you think it is helpful for reproduction. Also, if you need log files, etc, I am happy to pass them along.

What would be ideal would be for you to open a RH support case so we could work with you to track down the cause and a reproducer. Alternately, you could open a bug at bugzilla.redhat.com and work with it there if you're not able to open cases with our support people. If you do the latter, be sure to cc me on the bug and I'll see if I can help.
