Is client and AP far?...AP is receiving poorly and client is not getting you packets at all..
You are not receiving any ack from client and 41 from AP..Aireplay-ng with Death send out 128 packets for each deah you specify, 64 for Client and 64 for AP..
In you case you specified 10 deauth..From Client you have 0 acks and 41-48 from AP..Low numbers means is far away or link quality is bad.
Hope it helps..
