             Summary: DUCC Agent does not handle /bin/cgcreate failure properly on re-start when there are left over processes
                 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: future-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.
