[jira] [Closed] (UIMA-4898) UIMA-DUCC: Agent process killer not
working
[ https://issues.apache.org/jira/browse/UIMA-4898?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jerry Cwiklik closed UIMA-4898.
-------------------------------
Resolution: Fixed
An agent starts a timer to kill a process in case it fails to stop after SIGTERM is sent. When the timer pops the agent kills the process no matter what the current stat of the process is.

> When a child process fails to stop in response to SIGTERM the agent timer pops and SIGKILL signal is sent to a process. The timer thread does pop but it checks the state of the process before sending SIGKILL. It only allows this to be sent to process which is in a Running state. However the process may be in Initializing and Starting states and SIGKILL is never sent.
> Change the code to send kill signal no matter the state of the process is.
