Error message Network is unreachable

[dakiar]

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.

Dak.

are you running on a linux box ?
try adding -Djava.net.preferIPv4Stact=true in the Optional JVM args
also are you running a single node or clustered env ?

I am running a clustered server with 1 cluster. I am running on a linux box.

The -Djava.net.preferIPv4Stact=true appaers to not help :(

Can I find out where the exception is cooming from?

have a look here:

http://www.jboss.org/community/wiki/JGroups

look in the troubleshooting section. It's likely that you need to adjust multicast configuration.

hope it helps

Thank you, with the information there I managed to solve it! It was related to the IP stack just as you guessed!
