Hi All, I have installed JBoss AS 4.2.3.GA on AIX 5.3. I have made a copy of the "all" configuration and started up the AS using the newly created configuration. The startup give me the following error messages: 09:51:01,573 ERROR [UDP] max_bundle_size (64000) is greater than largest TP fragmentation size (8000) 09:51:01,574 ERROR [UDP] the following properties are not recognized: {enable_bundling=true, max_bundle_size=64000, max_bundle_timeout=30} 09:51:01,626 WARN [ServiceController] Problem creating service jboss.cache:service=TomcatClusteringCache org.jgroups.ChannelException: unable to setup the protocol stack I have done the exactly the same steps on HP-UX 11i (PA-RISC), HP-UX 11i (Itanium) and Solaris 10 (SPARC) and I do not encounter the same problem. I would appreciate it if somebody could please tell me how to resolve the above issue without changing the version of JBossAS.
