Alfresco: ObjID already in use

What a wonderful day, after hours of installation and customization procedure (Alfresco backend on Debian Linux host) i’ve got a killer error message in console.

Alfresco 3.0 startup error, with difficult to understand message about some object what is already in use:

18:46:21,943 ERROR [web.context.ContextLoader.initWebApplicationContext:203] Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.remoting.rmi.RmiServiceExporter' defined in class path resource [alfresco/emailserver/email-service-context.xml]: Invocation of init method failed; nested exception is java.rmi.server.ExportException: internal error: ObjID already in use

The next section of the error log, with network realated messages:

Caused by: java.rmi.server.ExportException: internal error: ObjID already in use
at sun.rmi.transport.ObjectTable.putTarget(
at sun.rmi.transport.Transport.exportObject(
at sun.rmi.transport.tcp.TCPTransport.exportObject(
at sun.rmi.transport.tcp.TCPEndpoint.exportObject(
at sun.rmi.transport.LiveRef.exportObject(
at sun.rmi.server.UnicastServerRef.exportObject(

And what is the solution? Very simple, just check your network and host – in /etc/hosts file – names and IP addresses, and correct to real values, what is showed by ifconfig command.

Java application wants to bind an IP address, but this address isn’t exists on system…
