exception=java.io.IOException: Network is unreachable, msg=[dst: 228.1.2.3:45566, src: se-ore-webp-test:32781 (additional data: 14 bytes) (2 headers), size = 0 bytes], mcast_addr=228.1.2.3:45566 I am running jboss on a server which does not have internet access, and keep getting this IOException, it appears to come from Jboss as I don't have any applications of my own deployed. Does anyone know what it means?? I guess I could disable it somehow? or make internet availaible and it would go away?? Thank you for clearing the confusion. Regards, Dak.
