Hello,

I was trying to benchmark network performance using Iperf3 version 3.1.3.

I see that when I use a high datagram length (-l) on UDP Protocol, the
receiver does not receive any packets and the bits per second at the
receiver side shows as 0.

I also tried to use the option "--udp-counters-64bit", the behavior
observed is still the same.

Command run on server: iperf3 -s --json
Command run on client: iperf3 -c server_ip --json -u -w 4m -i 1 --bandwidth
1000000000 -t 20 --length 30000 --get-server-output --udp-counters-64bit

We see after running for some seconds, the server stops receiving packets.

Do we know why this could be happening and what can be done?

Thanks,
Prachi
