> When collecting user processes running on a node, an agent uses a command similar to this:
> ProcessBuilder pb = new ProcessBuilder("ps", "-Ao",
>  "user,pid,ppid,args,stat", "--no-heading");
> When the above is run, linux truncates the user name to 10 characters. This effects code in the following classes:
> CGroupsManager.java, NodeMemInfoCollector.java, NodeUsersCollector.java
> Modify the command to use: user:32.
