>          Issue Type: Improvement
>          Components: Deployment / Scripts
>    Affects Versions: 0.9

>            Priority: Major
>
> Currently, the TaskManager processes may die under certain fatal exceptions that prevent the TaskManager to proceed.
> Most of those problems can be fixed by a clean process (JVM) restart.
> We can make the system more resilient by changing the {{taskmanager.sh}} bash script to restart the processes upon a certain exit code. 
> The TaskManager returns that exit code whenever it kills itself due to a problem that requires a clean JVM.
