We implemented a permanent fix. Here is our conclusion of the cause of the issue. At about 10:30 a.m. one of the mobile carriers started sending delivery status reports to our network repeatedly. This very likely occurred due to an error on their network. This caused that the inbound messaging should become full and the system wasn't able to pass a significant increase of requests at once. Therefore the messages were placed in a queue. We have reached out this mobile carrier. Their engineers have implemented a quick fix. However, while trying to clear the queued messages, some messages may have been received repeatedly because the sending carrier didn't receive the message acknowledgment when the request was made first attempt. The issue is now resolved.
