> Key: UIMA-5098
> URL: https://issues.apache.org/jira/browse/UIMA-5098
> Project: UIMA
> Issue Type: Bug
> Components: DUCC
> Reporter: Lou DeGenaro
> Assignee: Jerry Cwiklik
> Fix For: 2.2.0-Ducc
>
>
> Upon (re-)start of DUCC, one machine showed status as "defined" on the
> Machines page and "unknown" on Daemons page in ducc-mon.
> Examination of the Agent's log revealed:
> host.domain.net.agent.log:java.io.FileNotFoundException:
> /cgroup/ducc/327204.327204.28574/cgroup.procs (No such file or directory)
> Also, manually attempting to run
> /bin/cgcreate -t degenaro:mygroup -a degenaro:mygroup -g memory,cpu:ducc/test
> failed with:
> /bin/cgcreate: can't create cgroup ducc/test: Cgroup, operation not allowed
> This may be due to Agent attempting to clean-up processes from previous
> lifetime, but is unable to do so.
