Hi thanks for answer, I tried to increase JBoss heap size Xmx to 1024, but the problem is still there. I started the jboss in eclipse jboss server plugin, some part of the exception trace is here; | 13:44:35,031 INFO [PortletAppDeployment] Parsing /portal-core/jboss-portlet.xml | 13:44:36,500 INFO [PortletAppDeployment] Parsing /portal-cms/jboss-portlet.xml | 13:44:37,625 INFO [CMSPortlet] Cannot start CMS portlet search service due to service unavailability | 13:44:39,953 INFO [TomcatDeployer] deploy, ctxPath=/jmx-console, warUrl=.../deploy/jmx-console.war/ | 13:45:17,609 INFO [Http11Protocol] Starting Coyote HTTP/1.1 on http-localhost%2F127.0.0.1-8080 | 13:45:39,359 ERROR [STDERR] Exception in thread "ScannerThread" | 13:45:39,875 ERROR [STDERR] java.lang.OutOfMemoryError: Java heap space | 13:46:04,562 INFO [AjpProtocol] Starting Coyote AJP/1.3 on ajp-localhost%2F127.0.0.1-8009 | | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4074369#...
