-----------------------------------
Summary: DUCC Agent should detect defunct processes
Key: UIMA-3647
URL: https://issues.apache.org/jira/browse/UIMA-3647
Project: UIMA
Issue Type: Bug
Components: DUCC
Affects Versions: 1.0-Ducc
Reporter: Jerry Cwiklik
Assignee: Jerry Cwiklik
Modify agent to detect a defunct (zombie) process. When one is found, change
the state of the process to CROAKED and remove from inventory to mark it as
rogue.
The defunct processes appear to be running from the Agent's point of view as
the process never exited thus the Agent continues to wait in the
process.waitFor() and also consumes stdout and stderr. The only remedy for this
is to bounce the agent since there is no way to kill the defunct process which
is still owned by the agent.
