While the 2.6.32-696.23.1.el6.x86_64 is an old kernel, it is actually the current kernel for CentOS/RHEL 6. Red Hat has backported a lot of fixes to it and CentOS/RHEL 6 is a distribution that is still under maintenance.
It is still out there in a lot of places and has been in production for a while. That it is old, is a feature, it also means that it is incredibly stable.
Also note that the problem is also reported on a CentOS 7.4 kernel a few posts down.
