There is a kernel bug that causes a system crash when the uptime > 208.5 days. The patch is available:<br />
<br />
<a href="http://git.kernel.org/?p=linux/kernel/git/tip/tip.git;a=commitdiff;h=4cecf6d401a01d054afc1e5f605bcbfe553cb9b9">http://git.kernel.org/?p=linux/kernel/git/tip/tip.git;a=commitdiff;h=4cecf6d401a01d054afc1e5f605bcbfe553cb9b9</a> [<a href="http://git.kernel.org/?p=linux/kernel/git/tip/tip.git;a=commitdiff;h=4cecf6d401a01d054afc1e5f605bcbfe553cb9b9" target="_blank">^</a>]<br />

According to a post by an RH person, they are aware of the issue. If the patch does not come out immediately, adding this patch to the cplus kernel should be considered.<br />
<br />
However, in a way this is not urgent here because CentOS-6 is not "old" enough to get hit by this [otherwise serious] bug.
