Pool error connecting to database

[Mikel Lertxundi]

Hi,

I've made an aplication that conects to a database via mysql Connector/J 3.1.8 version and
I've this error when trying to connect to the Database:

java.net.SocketException: java.net.BindException: Address already in use: connect
at com.mysql.jdbc.StandardSocketFactory.connect(StandardSocketFactory.java:151)
at com.mysql.jdbc.MysqlIO.<init>(MysqlIO.java:280)

at controlmontaje.Principal.main(Principal.java:40)

It's weird but I´ve got this error time after several inserts are made to the database via JAVA aplication.

Thanks, and excuse my English I've got it a little bit rusty.
