Public bug reported:
Hello!
I've encountered the error while becnhmarking UDP traffic between two
instances. Any help would be apreciated.
I've got two instances (test1: 172.31.200.232, test2: 172.31.200.234)
located in one external network on separate compute nodes. Testing via
iperf3 brought me to fail:
root@test1:~# iperf3 -s
root@test2:~# iperf3 -c 172.31.200.234 -u
Connecting to host 172.31.200.234, port 5201
iperf3: error - unable to read from stream socket: Resource temporarily
unavailable
While, when I put together these instances on the same compute node,
everything is fine:
root@test1:~# iperf3 -s
root@test2:~# iperf3 -c 172.31.200.234 -u
Connecting to host 172.31.200.234, port 5201

My security groups allow UDP and TCP traffic.

Firewall_driver is 'openvswitch', can it be the cause?
Thanks,
