Thanks a lot Heiko, That makes lot of sense. So as I understand
1. If the JVM (where child actor resides) terminates(or crashes), no supervision applies. 2. The only way to recover then would be to start the process (JVM) with ChildActor again(manually or some other way) and parent Actor (in separate JVM) looks up for it and starts watching it again Correct me if this understanding is wrong Thank you + Harit Himanshu On Mon, Jun 22, 2015 at 12:08 PM, Heiko Seeberger <[email protected]> wrote: > You seem to confuse failure and termination.
