> Key: UIMA-3319
> URL: https://issues.apache.org/jira/browse/UIMA-3319
> Project: UIMA
> Issue Type: Bug
> Components: DUCC
> Reporter: Jerry Cwiklik
> Assignee: Lou DeGenaro
> Fix For: 1.0-Ducc
>
>
> When a process exits normally or terminates due to a kill not initiated by
> DUCC, the Agent marks the process as Failed with Reason Croaked. The agent
> has no way to determine if the process exited gracefully or due to an error.
> The return code from the process can be interrogated to see if the process
> was killed due to a signal. In such case, the high bit in the return code
> will be set. When the process exits not due to a signal is where the problem
> exists. No way of knowing why that happened. This is user code and as such
> cannot be relied upon.
> Modify the agent to change state of the process to Stopped instead of Failed.
> If the process was killed by an agent the reason should be KilledByDucc both
> for APs and JPs. If the process exited on its own, the reason should be Other.
