If the receiver suddenly has a memory allocation problem then it may close the window and this is allowed but not encouraged. If in this circumstance a packet is received I would expect that it would be held in a lower-layer buffer such as the NIC ring buffer and if that buffer filled then following packets would be discarded. I wouldn't expect any ICMP but would expect normal TCP congestion mechanisms. | |
