It's not an inevitable issue，It sometimes occurs more frequently in our production environment

Providing the appropriate unit test cases is difficult,we use callactivity , then ExecutionListener for setVariable , last GloablListener FlowableEngineEventType.TASK_ASSIGNED for ASSIGNED

There is no general issue with creating a sub process instance with a call activity in Flowable, so we need to be able to reproduce your issue in some way. Therefore a unit test showing the issue is required for us to further analyse this.
