-----------------------------------
Summary: 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.
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.
