CentOS 6 update 6 is several releases behind, you are missing about 18
months of security and bug fixes.... 6.9 is current

what version kernel and glibc are you running?

glibc-2.12-1.209, kernel-2.6.32-696.3.2 are the latest for CentOS 6

doing partial OS upgrades, where you update only some system components
takes you into uncharted territory, as only the complete latest set of
system packages is tested together, mixing newer system packages with
older components is risky and unsupported.
