Hii,
I am running benchmark code and on the receiver side after receiving some
number of packets(8000 so), it starts showing overflow errors ("DDDD") on
terminal.
Following is the system configuration
python benchmark_rx.py -f 1100M --args "addr=10.32.38.163"
--to-file=/home/ashokbandi/GNU/a_rx.txt --bandwidth=500000
Decreasing the bandwidth delays the error.
I tried changing buffer size by setting net.core.rmem_max and
net.core.wmem_max to 33445532 but to no avail.
Following is the screen shot of terminal
DDok: True pktno: 24116 n_rcvd: 9730 n_right: 9723
