The warning occurs if a response is received, whereby the corresponding request is not found. When your submit_multi request is send, a incrementing sequence number is added and stored. Also your EMSE (SMSC) send the response multiple times with the same sequence number. As the there is no answer possible on the submit_multi_resp, the SMSC should consider the response as send and processed.
