no error can be found in server.log, following is the only message available
oracle-glassfish3.0.1|javax.enterprise.system.std.com.sun.enterprise.v3.services.impl|_ThreadID=28;_ThreadName=Thread-1;|Cannot refresh Catalog : Connection timed out
Apparently glassfish is trying to retrieve update information from glassfish update center, by removing glassfishv3/glassfish/modules/console-updatecenter-plugin.jar files will solve the access issue
