Answer 1

Address already in use is that already your application instance is running/listening on the same port. If you are an ubuntu user
netstat -tulpn | grep YOURAPPNAME
This will give you the ProcessId which is running the instance in your system. Find the process Id number and kill the instance and start the application once again.
To kill
kill -9 PROCESSID

Answer 2

Are you starting two processes of your Java application on the same box? GemFire server by default opens up a port on 40404 to listen to client connections, so when you start more than two servers on the same box, the second one gets an Address already in use exception. Look the script used to start your application. You will need to provide a different port for each GemFire server you are trying to start. Using GemFireShell i.e. gfsh this could be done like so:
gfsh>start server --name=server1 --server-port=4045
Or, if there are no clients (i.e. peer-to-peer deployment of GemFire), you can disable listening to clients like so:
gfsh>start server --name=server1 --disable-default-server
