Hi Martin, First of all, thank's very much for your answer. What I find strange is that I had 5 subscribers on the same host (using epgm, the same multicast group and port number). For 4 of them, everything was fine but I had this assertion for the fifth one. If the problem is related to my network, the five processes should have been impacted, no?
Do I miss something?
