servers are using the same listen address and port???

[Mila Shanoy]

I am getting a weird error when trying to startup a managed server (Linux, WL6.1)
I am starting it with the command line:
startManagedWebLogic.sh managedapp http://adminapp:7001

Here is the error:
starting wls managed server...
Starting WebLogic Server ....
Connecting to http://adminapp:7001...
<Sep 3, 2003 2:55:56 PM EDT> <Emergency> <Configuration Management> <Errors detected attempting to connect to admin server at http://adminapp:7001 during initialization of managed server ( null:7001 ). The reported error was: < null > This condition generally results when the managed and admin servers are using the same listen address and port.>
<Sep 3, 2003 2:55:56 PM EDT> <Emergency> <Server> <Unable to initialize the server: 'Fatal initialization exception

What does it mean ".. managed and admin servers are using the same listen address and port"? I appreciate any ideas you might have.

Try to restart the linux box this will free up the port locked .
