The reason is mkdir() call doesn't consider 700 as an octal value until unless 0 is explicitly added before the value. Because of this, socket creation failure is observed when DPDK application was ran in non root user mode. DPDK application running in root user mode never reported the issue. So 0 is prefixed to the value to create directories with the correct permissions.
