P.S. this is going to be more interesting to figure out since today was my last
day at this job. This is an interesting challenge, so I'm still going the help
the guys who are still there, but I no longer have direct access to things
there.
I need to try and duplicate this problem on the Ubuntu machines I do have
access
to, but it will take me a couple days to get time to do so, so if Eric can
check
on the RHEL systems we can keep making progress.
