I think you might be seeing a race condition. Whichever branch of the fork finishes first ends the process. If so you need a join before the end if you want both branches to be executed. It might be that one finishes before the other is even scheduled to run by the job executor.

The engine tests scenarios similar to this under Activiti/ParallelGatewayTest.java at develop · Activiti/Activiti · GitHub and the BPMN for those tests is at Activiti/activiti-engine/src/test/resources/org/activiti/engine/test/bpmn/gateway at develop · Activiti/Activiti · GitHu… I don't see your specific scenario of two service tasks on different sequence flows out from the fork but I think that's because you need to either have a join or have something that will stop the flow like a manual task in the branch in order to avoid a race condition. But if you're confident this condition can and should be addressed by the engine then it's an option to try to find an example out there of this scenario working and/or create a test case and see how to accommodate it with Activiti.
