> When an AP 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 AP was killed by an agent the reason should be KilledByDucc. If the process exited on its own, the reason should be Other.
