NAKACK messages fills JBoss logs after startup

Hi All, I am configuring a third party application based on JBoss, using application clustering with JGroups. However I am experiencing errormessages in the server logs that I don't quite understand, as below: ============== :UpHandler (NAKACK):org.jgroups.protocols.pbcast.NAKACK:2009/11/04-14:08:20.416 CET: message did not contain a list (LinkedList) of retransmitted messages: java.lang.IllegalArgumentException: java.io.IOException: java.lang.ArrayStoreException: org.jgroups.stack.IpAddress ============== What does this message mean? Are the nodes not capable of communicating? We got three nodes on the same machine multicasting eachother. As for testing multicasting with org.jgroups.tests.McastReceiverTest and org.jgroups.tests.McastSenderTest, seems to work ok when starting up the sender first. Starting the sender last will instead give me an infinite loop of "Hello from bela" on the receiver side. Is this expected? Using different bind_addr does not make any difference in the application server. We are using Solaris 10 machines. Used to have 2 or more NICs, but tests with only one interface gives the same result. BR, Cenk ATTENTION: This e-mail may contain confidential information that is intended solely for the addressee.

Sorry, I don't support 2.2.7 anymore, that's way too old !
I support 2.4.x, 2.6.x and (soon) 2.8.x only cenk.oguz@... wrote: >> Which version of JGroups ?
