How to handle Zombies in a non-deterministic orchestration?

Question

I am creating a non-deterministic orchestration to handle convoys. I know I am setting up for the classic 'zombie' pattern. What have you done to handle the zombies when this sort of pattern is necessary?

Answer 1

First point is make sure that it really necessary, can you avoid it? Read this first:

Only thing I can think of, is that you have a routine for monitoring and cleaning up suspended instances.
