--------------------------------------

Hi,

I am also facing this issue on Cent OS 6.3 nodes. I tried to upgrade kernel and libcgroup to CentOS 6.7 versions, but hit the same problem.
Currently out of option (RHEL 7 upgrade don't seem plausible), but I need to have a CPU isolation mechanism because otherwise some jobs launched on our platform just take too much resources and I see tasks failures and some jobs failures too.
[~Naganarasimha], is it possible to have a grasp of what your solution based on CPUset is ?

> With YARN-2440 and YARN-2531, we have seen some kernel panics happening under heavy pressure. Even with YARN-2809, it still panics.
> We are using CentOS 6.5, hadoop 2.5.0-cdh5.2.0 with the above patches. I guess the latest version also has the same issue.
