I have seen the http://forums.activiti.org/content/process-failover-cluster thread, but I am a little curious as to how failover works on a single node. Let's say that I have a process with 9 service tasks. I make the 1st, 4th and 7th service tasks asynchronous. Let's say that the 5th task is about to be started when the node goes down. When it comes back up, how is reinitiate of the process handled? Where does execution start? And how does one monitor which processes have failed and/or succeeded?
