> Key: UIMA-4585
> URL: https://issues.apache.org/jira/browse/UIMA-4585
> Project: UIMA
> Issue Type: Bug
> Components: DUCC
> Affects Versions: 2.0.0-Ducc
> Reporter: Jerry Cwiklik
> Assignee: Jerry Cwiklik
> Fix For: 2.1.0-Ducc
>
>
> Looks like an Agent is not calculating CPU percentage correctly when running
> with cgroups and JP spawns child processes. It correctly iterates over all
> processes in the cgroup but it keeps collecting CPU from the JP stat file in
> the /proc file system.
> To fix this, while iterating over procs in the cgroup, open process stat file
> to read the CPU. Make sure to close the file when done.
