The default for the parameter scheduler_job_chain is not scheduler_sosftp_history but the name of the job chain where the actual order is running. It should be =scheduler_sosftp_history

When using the background server an order is created to save the transfer in the database. The name of the job chain can be configured with parameter scheduler_job_chain. The default for this parameter should be scheduler_sosftp_history. But when the parameter is not specified, the name of the job chain is taken that belongs to the order which startet the transfer.
