Is there any restriction to the number of process that can join a multicast group when using ZeroMQ epgm transport.
I'm using loopback interface in EPGM as of now. zmq_connect(subscriber,"epgm://127.0.0.1;239.192.1.1:5555);
All the processes are on same Linux machine. Is there any restriction to the number of processes that can communicate (send as well as receive messages) over this interface.
