You have other apps running on the same multicast address and port in the same network, change your config and this will go away
Thanks for your help.
I got exactly the same problem but the fact is that this 'other application using same adress/port' is the Group I want to join ... !!
Are all versions of jBossCache / JGroups compatible ?
Thanx a lot.
All members in the same group ned to use the same JGroups/JBossCache versions.
Regarding versions of JGroups that are compatible with specific versions of JBossCache, see http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossCache
