Going by the compat.linux.osrelease sysctl, it is currently providing the kernel interface of Linux kernel version 2.6.32 (the one that ships with RHEL6). Similarly, the GNU userland that can be installed is based on CentOS6.
So, if your application requires newer kernel interfaces that were introduced in 3.x or 4.x, it will not work.
