If your kernel version is 3.10.0-123 then you are *way* backlevel. That is the original 7.0 kernel and the rest of your system is likely to also be at the same 2.5 year old level. You should `yum update` and retest on 7.3.

I upgraded the kernel version to 4.11.1-1.el7.elrepo.x86_64 #1 SMP Sun May 14 11:54:29 EDT 2017 and performed the tests. However the result remains unchanged - the test hangs. I can provide the complete log file if required.
You really should have run "yum update" to get your system updated, instead of installing a non-CentOS kernel. This makes it more difficult for others to reproduce your results. In addition to the kernel, you may also have glibc and other libraries from the 7.0 era. A simple "yum update" would have fixed that.
My recommendation would be to set up a fresh CentOS 7.3 system, run "yum update" without installing any 3rd party repositories, reboot, and then try to reproduce the issue on that system.
