Jerry Cwiklik updated UIMA-3319:
--------------------------------
Description:
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.
