Hello, we try to run JBoss 4.0.3 on Solaris 9, on a 24 CPU Fujitsu/Siemens. It works perfectly using Java 1.4, but with Java 1.5/1.6 the JBoss process consumes up to 35% CPU time (8 CPUs of the 24 available!) during startup. (We then kill the process(after 2/3 minutes), it would finally make the machine totally unavailable) We have no problems running the same installation on a 2-CPU Solaris 9 machine aswell as on the WinXP computers we use for development. I guess Java 1.6 may not be supported by version 4.0.3 but 1.5 should work without any problems, right? Any help/ideas greatly appreciated thanks in advance Karl View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4069492#...
