Why is there a distinction between an action and a blocking action? What kind of concerns arise when you send a potentially blocking action to an agent and why is send-off better accommodated to deal with it?
send serves the agent from a fixed ThreadPool. When all threads in this ThreadPool are used up, your agents basically freeze waiting in a queue for free threads. The number of threads in this ThreadPool is limited. send'ing a blocking action basically blocks the thread. Enough blocking threads might use up all threads and there you go. send-off allocates a new thread in a different ThreadPool. So the aforementioned scenario cannot happen. A Guru might want to give the details of the second scenario. Sincerely Meikel
