UDP packets are not reaching samplicator's reachable destinations when number of unreachable destinations are more than 1

[DipalPrajapati]

While using samplicator , we are facing packet loss in below scenario:

UDP packets are not reaching samplicator reachable destinations when number of unreachable destinations are more than 1

Configure 2 unreachable destinations for UDP port 1000 in samplicator config. Example in below configuration dest1 and dest2 are reachable destinations. dest3 and dest4 are unreachable destinations

receivers: "dest1/1000,dest2/1000,dest3/1000,dest4/1000"

Sending high volume of data e.g. 10 KFPS on source port 1000, and then check number of packets being received on reachable destination.

time sudo tcpdump -i eth1 src dest1 and udp port 1000 -B 26214400

We observed packet loss on reachable destinations.

Any idea about this behavior @sleinen?
