That's what I figured. The kernels have not been upgraded. The kernel
version changes from distribution to distribution and the actual version
of the distro.

That was a good suggestion, but we're not running vmware. I'm trying
to get one of our sysadmins to upgrade the kernel.

That's what I thought too, but I was wondering is someone else knew
more about this issue. I'll let everyone know if a kernel upgrade
helps.

Thanks to everyone for the feedback,
