[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=16200450#comment-16200450 ] Jerry Cwiklik commented on UIMA-5611: - An agent should check status of a process after kill -9 is issued to detect defunct a process. It should exec a ps command and parse the output to test for defunct. if one is detected, the agent should mark such process as Stopped and add Reason=Defunct. > UIMA-DUCC: Agent fails to kill a child process sometimes > > > 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.
