when can't get instance of Hazelcast, better idempiere should work normal like on standalone mode

reading the comments seems this can be closed - please reopen if there is still an issue

figure out how dns keep many port:
http://serverfault.com/questions/558104/dns-exe-allocates-5000-ports-immediately
http://support.microsoft.com/en-us/kb/953230
just change config to <multicast-port>60327</multicast-port>

figure out other case:
don't know why my dns service keep many port (almost all port) include port 54327, so when join multicast make exception => can't issue a hazelcast instance

can't detect root cause, but it seem by environment, because i close this issue.

1. with message description in forum, testing solution advice at http://stackoverflow.com/questions/3947555/java-net-socketexception-unrecognized-windows-sockets-error-0-jvm-bind-jboss
add -Djava.net.preferIPv4Stack=true

2. last tonight i has other case. my machine is a refresh mint os. just re-install
line multicastSocket.joinGroup(InetAddress.getByName(multicastGroup));
in class com.hazelcast.instance.Node make below exception
java.net.SocketException: No such device

after investigate, it's by i has none connecting network.
seem setup a loopback network with support multicast maybe resolve but i don't try.
i setup hamachi (a VPN software) and it also resolve issue
(hamachi must start, not need has a real connection)
