What does this Gconf error msg mean?

Whenever, I use ctrl-alt-f1 to go back to the command line, or when the system is shutting down I see this error message:
Code:
"GConf error:Failed to contact configuration server;some possible causes are that you need to enable TCP/IP networking for ORBIT,or you have stale NFS locks due to a system crash.see http:...Detail -1 failed to get connection to session:Unable to create socket."
