We are creating process instance using the below camunda provided API.
restservices/engine-rest/v1/engine/default/process-definition/key/ProcessId/start
We are seeing peculiar behavior in some cases that one process instance data is available on other’s execution. That data we didn’t provide in request. This is happening only when we are starting two instances almost at the same time.
This issue is not occurring when there is no load.
My BPMN process doesn’t have any parallel gateway or call activity. It is a simple BPMN with service task, exclusive gateway and one DMN file.
Is there any scenario available where two concurrent running process instances can share the data?
