I think I know what is happening... I have had this problem with Ubiquiti radios for a bit now. That looks like a flood of RX pause packets from flow control. The MT will see the PPS but you will not find anything on torch because it is at the switch layer.
If you have a smart switch there I would strongly recommend finding what port it is originating from. I bet it is from a UBNT Radio. Then a simple fix would be disable the flow control on that device.
