Craig Condit commented on YARN-4048:

Just my two cents: Using cgroups on CentOS/RHEL 6.x is asking for it... We've 
experienced similar crashes using anything that utilizes cgroups, not just YARN 
(for example -- docker).

Cgroups is widely regarded as unstable in Linux kernel versions < 3.10 or so.

>             Project: Hadoop YARN
>          Issue Type: Bug
>          Components: nodemanager
>    Affects Versions: 2.7.1
>            Reporter: Chengbing Liu
>            Priority: Critical
>         Attachments: panic.png
> 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.
