Each sub-process will have multiple asynchronous task.&nbsp; We noticed an issue when multiple sub-process finish in the same time: we get errors like ActivitiOptimisticLockingException and the activiti engine will retry the s Wed, 28 Oct 2015 15:00:16 GMT https://connect.hyland.com/t5/alfresco-archive/problem-caused-by-multiple-asynchronous-sub-process-finishing/m-p/202951#M156081 domreiroam 2015-10-28T15:00:16Z Re: Problem caused by multiple asynchronous sub process finishing around the same time. https://connect.hyland.com/t5/alfresco-archive/problem-caused-by-multiple-asynchronous-sub-process-finishing/m-p/202952#M156082 <HTML><HEAD></HEAD><BODY><SPAN>If you have multiple servers and fire jobs for the same process instance, then optimistic locking is expected. You could solve it by making them exclusive (but with multiple servers it might still happen). The reason why H2 doesn't show it could be because H2 has a much more coarse locking vs 'real' databases.</SPAN><BR /><BR /><SPAN>The unit test would be fantastic to understand. You can indeed create an issue and attach it.</SPAN></BODY></HTML> Wed, 28 Oct 2015 19:39:29 GMT https://connect.hyland.com/t5/alfresco-archive/problem-caused-by-multiple-asynchronous-sub-process-finishing/m-p/202952#M156082 jbarrez 2015-10-28T19:39:29Z Re: Problem caused by multiple asynchronous sub process finishing around the same time. https://connect.hyland.com/t5/alfresco-archive/problem-caused-by-multiple-asynchronous-sub-process-finishing/m-p/202953#M156083 <HTML><HEAD></HEAD><BODY><SPAN>We have the problem with only one server and we did reproduce in a junit using the last version (5.18)</SPAN></BODY></HTML> Wed, 28 Oct 2015 19:57:06 GMT https://connect.hyland.com/t5/alfresco-archive/problem-caused-by-multiple-asynchronous-sub-process-finishing/m-p/202953#M156083 domreiroam 2015-10-28T19:57:06Z Re: Problem caused by multiple asynchronous sub process finishing around the same time. https://connect.hyland.com/t5/alfresco-archive/problem-caused-by-multiple-asynchronous-sub-process-finishing/m-p/202954#M156084 <HTML><HEAD></HEAD><BODY><SPAN>I just create </SPAN><A href="https://activiti.atlassian.net/browse/ACT-4083" rel="nofollow noopener noreferrer">ACT-4083</A><SPAN>.</SPAN><BR /></BODY></HTML> Thu, 29 Oct 2015 17:25:27 GMT https://connect.hyland.com/t5/alfresco-archive/problem-caused-by-multiple-asynchronous-sub-process-finishing/m-p/202954#M156084 domreiroam 2015-10-29T17:25:27Z Re: Problem caused by multiple asynchronous sub process finishing around the same time. https://connect.hyland.com/t5/alfresco-archive/problem-caused-by-multiple-asynchronous-sub-process-finishing/m-p/202955#M156085 <HTML><HEAD></HEAD><BODY><SPAN>Ok, thanks.
