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 Mon, 25 Nov 2013 19:31:42 GMT https://connect.hyland.com/t5/alfresco-archive/how-process-failover-is-handled-on-single-nodes/m-p/165121#M118829 hiravgandhi 2013-11-25T19:31:42Z Re: How process failover is handled on single nodes https://connect.hyland.com/t5/alfresco-archive/how-process-failover-is-handled-on-single-nodes/m-p/165122#M118830 <HTML><HEAD></HEAD><BODY><SPAN>Activiti commits the database transaction when it reaches a wait state (like a user task or an asynchronous task) or when the process is ended.
