[ https://issues.jboss.org/browse/JGRP-1617?page=com.atlassian.jira.plugin.... ] Dan Berindei commented on JGRP-1617: ------------------------------------ Bela, I was able to reproduce the timeout using your test, with this modification: {code} Message msg = new Message(); msg.setDest(b.getAddress()); RspList<Object> rsps=disp.castMessage(null, msg,RequestOptions.SYNC()); {code} It seems that, if the destination address is already set in the message, UDP will only send the message to that address, but MessageDispatcher will still wait for responses from all the members of the cluster. I think at the very least this should warrant a warning. -- This message is automatically generated by JIRA.
