Some time later ... I receive this exception
20:33:29,817 ERROR [UDP] exception=java.io.IOException: Message too long, msg=[dst: 10.200.200.31:35346 (additional data: 18 bytes), src: b2:34301 (additional data: 18 bytes) (2 headers), size = 81165 bytes], mcast_addr=18.104.22.168:45566
Me too I am facing the same problem. Please let me know if you resolve the issue.
check for these:
1. As using same version?
3. Mcast is working properly?
I have the same problem. Single that reproduces of random form. It happens later to works well during several weeks.
