----------------------------------
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.
