I am still getting this problem too. Thought it was fixed but now it has come back to haunt me :-(
When I start JBoss 3.0.0 RC2 (Branch_3_0_0), I get the following error and then JBoss hangs. The only way I can stop it is to kill the CMDTOOL, or kill the Java process but this causes plenty of JVM_Bind errors when I restart. I have changed the Port (as suggested), reboot, run JBoss as the first thing once logged in and I get the following: 14:17:33,259 INFO [MainDeployer] Successfully completed deployment of package: file:/H:/EvoDev/jboss-3.0.0RC2/server/default/deploy/hsqldb-service.xml 14:17:33,279 INFO [MainDeployer] Starting deployment of package: file:/H:/EvoDe v/jboss-3.0.0RC2/server/default/deploy/iiop-service.xml 14:17:33,320 INFO [STDOUT] Server.run/init: java.net.BindException: Address alr eady in use: JVM_Bind 14:17:33,320 ERROR [STDERR] java.net.BindException: Address already in use: JVM_ Bind 14:17:33,320 ERROR [STDERR] at java.net.PlainSocketImpl.socketBind(Native Me thod) 14:17:33,320 ERROR [STDERR] at java.net.PlainSocketImpl.bind(PlainSocketImpl .java:321) 14:17:33,320 ERROR [STDERR] at java.net.ServerSocket.bind(ServerSocket.java: 308) 14:17:33,340 ERROR [STDERR] at java.net.ServerSocket.bind(ServerSocket.java: 266) 14:17:33,340 ERROR [STDERR] at java.net.ServerSocket.<init>(ServerSocket.jav a:182) 14:17:33,340 ERROR [STDERR] at java.net.ServerSocket.<init>(ServerSocket.jav a:94) 14:17:33,340 ERROR [STDERR] at org.hsqldb.Embedded_Server.run(Embedded_Serve r.java:145) 14:17:33,340 ERROR [STDERR] at org.hsqldb.Embedded_Server.main(Embedded_Serv er.java:92) 14:17:33,350 ERROR [STDERR] at org.jboss.jdbc.HypersonicDatabase$2.run(Hyper sonicDatabase.java:186) 14:17:33,590 INFO [CorbaORBService] Creating 14:17:33,590 INFO [CorbaORBService] Created 14:17:33,590 INFO [CorbaORBService] Starting 14:17:33,960 ERROR [STDERR] [ Listener: Couldn't initialize.
