[jira] [Commented] (UIMA-5611) UIMA-DUCC: Agent fails to kill a
child process sometimes
[ https://issues.apache.org/jira/browse/UIMA-5611?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16199493#comment-16199493 ]
Burn Lewis commented on UIMA-5611:
----------------------------------
These became defunct processes so kill -9 won't help ... perhaps agent should treat them as gone.

> Key: UIMA-5611
> URL: https://issues.apache.org/jira/browse/UIMA-5611
> Project: UIMA
> Issue Type: Bug
> Components: DUCC
> Reporter: Jerry Cwiklik
> Assignee: Jerry Cwiklik
> Fix For: 2.2.2-Ducc
>
>
> Improve detection of child processes which fail to stop after kill -9 was sent. If kill -9 is sent by an agent while a child process is experiencing an OOM, the signal is not acted upon and the process remains running.
> An agent should retry kill -9 on regular basis (configured in ducc.properties) if a process is still standing after kill -9.
