Workflow stuck in activity "Timer"Description Workflow Timer activity, schedule job or async business rules are not executing even when the worker threads are idle.CauseThe most possible cause in this situation can be the instance being in a paused state. In order to check if the instance is in a paused state. Navigate to System Definition>scripts - Background and run the below code gs.print(gs.isPaused()); ResolutionIf the Result is "true" then you need to restart the instance and if the result is "false" you can investigate the issue from a different perspective. Additional InformationWhen the sys_trigger table is accessed you can observe the activities are in ready(in red color) state and the time for the next action is also completed. When opened the activity and clicked on "Execute Now" the activity next action date and time changes but it is still in Ready state only.
