When several synchronous Child IPC processes are called by a parent workflow, these processes complete successfully without any errors and with a ‘Completed’ status. However, the activities in the parent process do not complete and remain on an ‘Active’ status.

Error Scenario

Note: The circumstances described in this article are one scenario under which this issue may, or is known to occur. The description is intended to be specific to the scenario described and does not take into account all possible scenarios or circumstances.
  1. Create a process with a couple of synchronous IPC events
  2. Create multiple lines so that all the IPC events are active at the same time
  3. Add events after the IPC events to slow down execution within the parent process
  4. Add at least one Client event in the child processes
  5. Deploy and start multiple instances of the parent process
  6. Action all the worklist items created by the child processes
  7. Some parent processes will not finish although all of the child processes are complete

Error Message

No error message but the problem is evident from inconsistencies within the state of the parent process.
