We recently encountered a bug in standalone that results in processors running with inconsistent job model.
Here is a document <https://docs.google.com/document/d/1gWjKsbNoRwuSexjAxgqw_1R9MaJEckMIZY0cX2_NoaY/edit?usp=sharing> that describes the problem and proposes few approaches to fix the problem. Please let me know your thoughts. -- Bharath
