Puppet is great, for sure. In this specific case, I'm not sure it would
have helped. It's still easy to have drift of packages versions in a
Puppetized environment if you aren't methodical about rolling out
updates. This is especially true for packages like the kernel, which
require intervention for the update to take effect. To solve this within
puppet, I suppose you could have it ensure that only a specific kernel
version was installed, or have it manage your GRUB configuration and
specify a specific kernel version to boot. It may be smarter to solve
the problem at the repository level.

a high degree of confidence that it would be identical to the other
servers in your environment and you wouldn't have seen this issue!
Glad you it got you working! And people say RedHat support isn't worth
it! ;)

If you don't have access to this KB article let me know and I
can print
it out for you. Looks to be a kernel bug. A quick cut and
paste of the
workaround section:
This issue is resolved in |kernel-2.6.32.358.16.1.el6| and later.
Please update the kernel package with |yum update kernel|.
Workaround
Run the following command as the root user:
|echo 1 > /proc/sys/vm/unmap_area_factor
|
If this resolves the issue, then add the following line to
|/etc/sysctl.conf| to persist the change across reboots:
|vm.unmap_area_factor = 1
|
Kent,
I owe you a steak and a beer!
I did the yum update kernel and the problem is solved!
Case closed.
Honorable mention to Brian.
