I tried with latest release of LTP on the same affected machine and I did not observed any test case or system hang. I hope you are using latest LTP downloaded from 'ltp.sourceforge.net'? There might be a issue with oom that it is not able to kill the memory intensive process but you need to gather more information about the hanging process first. You might want to run only the hanging test i.e. memcg_stress and not complete LTP to narrow down the issue. Just check whether you are able to reproduce the issue when only memcg_stress test is running There are chances that test case itself has some issues.
